Please see the tables below for an introduction and short-cuts into the functions of Survey Builder.
Scripts are used to provide special functions that are not part of the built-in logical language of Survey Builder. Scripts can be used in filters, answer control and reference to questions.
In Survey Builder scripts are implemented in C#. Function names follow a standard naming syntax, and in general functions do not have fixed numbers of parameters. E.g. script:Sum(1,2,3,4,5,6,7,8,9) will sum 9 numbers.
NB: Use your mouse or the arrow keys to scroll left/right - it may be easier to copy and paste these tables into Excel.
| Script | Description | Parameters | Examples |
| AdjustTime, TimeAdj | Modify the current time by the number of hours provided. | script:AdjustTime(parameter1) | script:AdjustTime(2) |
| Positive and negative numbers can be provided. | script:TimeAdj(parameter1) | script:TimeAdj(2) | |
| This will add two more hours on top of the current time (GMT) | |||
| AdjustTimeNowH, Adj_TimeNowH | Returns the current time in the same format adjusted by the number of hours specified. | script:AdjustTimeNowH(parameter1) | script:AdjustTimeNowH(2) |
| script:Adj_TimeNowH (parameter1) | script:Adj_TimeNowH(2) | ||
| Retuns the time in required format | |||
| AdjustTimeStartF, Adj_TimeStartF | Returns the questionnaire start time adjusted by the number of hours specified. | script:AdjustTimeStartF(parameter1) | script:AdjustTimeStartF(020202) |
| On a format of hhmmss. Can be used in data type: Numeric | script:Adj_TimeStartF (parameter1) | script:Adj_TimeStartF(020202) | |
| Retuns the new time in required format with adding the 2 hours, 2 minutes and 2 seconds to the current time | |||
| AutoCode | It is possible to add pre-filled text from an Excel-file to a survey. | https://static.quenchtec.net/46033bcf-0124-4b26-b4ea-30726bd5357c/54SRV1uNcvN/Check-ZIP-CITY.xlsx | |
| For example, we have a question in the survey asking for a ZIP code. Then we the Excel file where the ZIP code will be verified, and then it provide us the CITY automatically. | |||
| You need to create an Excel file, with all the ZIP codes, and then a column for CITY. | |||
| There must be a sheet called Sheet1, in the header above all columns following normal "variable" conventions, e.g. just use a-z, 0-9, like "amount", "age" etc (no spaces). | |||
| All columns should be formatted as text fields, even though they contain numbers. You need some column to use as the lookup column, e.g. a company "number". | |||

| CreateShortURLKey | Returns the 8 number/characters that should go after https:\\url.quenchtec.net | script:CreateShortURLKey([any_link]) | script:CreateShortURLKey([any_link]) |
| This will return the 8 number/characters that should go after https:\\url.quenchtec.net | |||
| That way in redirects, email invites send form a survey etc, | |||
| You can use a short link rather than the long https://quenctec.net/p?qis=....&qif=.... etc | |||
| CurrentAge | Calculates the age based on yearBorn and this year | script:CurrentAge(yearBorn,thisYear) | script:CurrentAge('1990',\@sys_year) |

| v0, v1, v2 .... values to be substituted, can be strings or addresses to questions etc | |||
| FromTo | Set a range between the "from" value and the "to" value. | script:fromto(from,to) | script:fromto(0,\Q2.a.1) |
| It will return an "interval" that can be used in answer control, like "0:100" restricting the user to enter a value between 0 and 100. Typically one or both parameters are references to other numeric questions where they previously have entered a value. | Will return a interval from "0" to the answer from "Q2.a.1" (this needs to be a numeric question). If the answer to "Q2.a.1" is 230, it will return "0:230" | ||
| HashSum | Creates a range, typically to be used on numeric questions that represents a sum | script:HashSum(sumValue) | script:HashSum(100) |

| end - Last value to pick from | |||
| NumberToPick - How many random numbers do we want to pick | |||
| randomSeed - Seed to be used | |||
| RandomSingleFromList | Pick a single random number from a list for random generated numbers. To be used when you want a series of "unrelated" random numbers, where you then can pick one by one of these to be used in various questionnaire logic. The function first creates a list of random numbers and then return the one you selected from the list. | script:RandomSingleFromList(RangeStart,RangeEnd,RangeCount,Seed,Item) | script:RandomSingleFromList(1,1000,10,\@sys_random,5) |
| RangeStart - Specify the lowest possible random number you want created in the list | This will generate a list of 10 random numbers between 1 and 1000, using sys_random as seed, and return the 5th item in the list. If the list is "311,451,486,506,539,639,738,871,903,963" the 5th item is "539". | ||
| RangeEnd - Specify the largest possible random number you want created in the list | |||
| RangeCount - Specify the number of random numbers you want created in the list (this number should be less than the interval defined by the RangeStart-RangeEnd | |||
| Seed - Specify a seed to be used for the random generater. Typically you will use the "sys_random" variable that is a random number between 0 and 1000 created at the start of an interview. This will ensure that the list of random numbers will the same for one given respondent. | |||
| Item | |||
| Specify the item you want returned from the list | |||
| Redirect | The most common URL type is what we call "Parameter based". This structure has a "base URL", followed by a "?" (question mark), followed by one or more pairs of parameters that have a "name" and "value" separated by "=" (equal sign). Each pair, in turn, is separated by a "&" (ampersand sign). | script:redirect(baseurl,p1,v1,p2,v2,p3,v3........) | script:redirect('https://yourlink.com','survey','XYZ123') |
| The other not-so-common type is what we called "Path-based". This structure just have a series of values, separated by "/" (slashes). This type should not have any special symbols like "?", "&", or "=" as part of the URL. | Where p1 = parameter1 and v1 = value1, etc. | ||
| Finally, there also exists some "Hybrid based" structures, that do not adhere to the common ones. These are quite rare. | Using this script it is very important to remember that there should be NONE of the special symbols used to create the URL, like the "?", "&" and "=". These are ALL inserted at appropriate places by the script. | ||
| lf(QID, flt, numToPick, randomseed) | This function is used to run real-time analysis on a dataset (questionnaire) to determine the counts for the options (categories) in the question. Based on the counts, and the codes qualifying, one or more categories are picked based on a least-fill (the categories with the lowest counts are picked first). In principle, the analysis dataset can be a different one than the one we are programming, and the analysis question can be a different one from the one we are in, so there is no automatic connection between the question/questionnaire we are in and the script function. Hence, all parameters must be carefully considered. Also the difference between static parameters that are in single quotes, and dynamic/references that are not in single quotes and are typically introduced by "\" (backslash character). | lf(QID, flt, numToPick, randomseed) | script:lf(LF.a,\L1.a,2,\@sys_random) |
| QID: Question ID to be punched | |||
| flt: This is a reference to the question that contains the qualifying codes (options). This must always be a reference, aka it should NOT be in single quotes, and always start with a ""\"". Usually, this is a sub-question within the question we are programming, and hence we can use the shorthand notation like ""\.a"" meaning the subquestion a (first subquestion, within the question we are programming. | |||
| numToPick: This is the maximum number of categories that we should pick of the ones qualifying. | |||
| randomSeed: This is a seed used by the random generator to pick randomly, if more several options have the same counts, or if the analysis fails. | |||
| Returns the lowest value from a question to determine which answer/cell needs to get selected" | |||
| SelectFirstN | Typically used to select a codes from a multi-choice question | script:SelectFirstN(ListToPickFrom,IndexToPick) | script:SelectFirstN(\BrandsKnown.a,1) |
| ListToPickFrom - Typically reference to a multiple-choice question | Result: 3 - if 3 is the first code selected in question \BrandsKnown | ||
| IndexToPick - One based index of code to pick | |||
| SelectN | Pick the "Nth" value from a multiplechoice question | script:SelectN(MultipleChoiceQuestion,valueToPick) | script:SelectN(\Brands_Known.a,2) |
| Result: Returns the second code the respondent gave to question BrandsKnown | |||
| SelectOneFromList | Returns one value from a list of values. The index is one based. Typically used in combination with "MinIndex" and "MaxIndex". | script:SelectOneFromList(index,v1,v2,v3....) | script:SelectOneFromList(1,\q1.a,\q2.a) |
| Result: Returns the value from Q1 | |||

| NumberToPick - How many codes should we pick | |||
| randomSeed - Seed to be used if more codes than we request are | |||
| SelectTopXFromRows | Typically used in a grid question, to select a number of rows that should be used later, based on the code value of the row. | script:SelectTopXFromRows(v1,v2,v3,v4,v5.....numberOfRowsToPick,maxValueToPick,randomSeed) | script:SelectTopXFromRows(\grid.a.1,\grid.a.2,\grid.a.3,\grid.a.4,2,5,\@sys_random) |
| v1,v2,v3... - Tyically reference to the row 1,2,3 etc of a grid question | |||
| numberOfRowsToPick - How many rows should we pick (e.g. top 5) | |||
| maxValueToPick - The highest code-value that we want to include in the pick (e.g. to avoid picking "99 - None of these" | |||
| randomSeed - Seed to be used to pick if we have multiple rows with the same value that qualifies | |||
| SingleAutoCode | Looks for "needle" in the hash (#) delimited string "hasSepListIn", if found, returns the corresponding value form "hasSepListout", if not found, returns "notFoundValue". | script:SingleAutoCode(needle,hashSepListIn,hashSepListOut,notFoundvalue) | script:SingleAutoCode(\@sys_lang,'en#dk#se#no','1#2#3#4','99') |
| Result: 2 if \@sys_lang=dk, if not found, 99 | |||
