Hi, I'm looking to see if I can do 2 things with LimeSurvey:

1) I have a multi-numeric slider question, with min-max limits. Is it possible to use the "sum" value from this question, as the maximum amount of answers someone can select in the following question?

E.g.

Q1. How many bars did you eat? (User enters total sum of 3 out of possible 5)

Q2. How many did you enjoy? (Maximum answers dynamically reduced to 3 from 5)



2) The second query is: What is the syntax for targeting multiple subquestions with a regexMatch?

To target a single subquestion, I'm using the following:

- Question validation equation: (regexMatch('/([A-Z]{1}\d{1,2})/',Q24_1))
- Question validation tip: {if((regexMatch('/([A-Z]{1}\d{1,2})/', Q24_1)),'','Please enter a valid grid reference.')}

Ideally it would be something like this (this example breaks the syntax):
(regexMatch('/([A-Z]{1}\d{1,2})/',Q24_1, Q24_2, Q24_3, Q24_4, Q24_5, Q24_6))

I've attached the lss file for what I'm trying to get working

1) If you place the two sliders on separate pages, you can use the value of Q1 as the "Slider maximum value:" for Q2.


2) Why not use the "Sub-question validation equation:"?

1) If you place the two sliders on separate pages, you can use the value of Q1 as the "Slider maximum value:" for Q2.

Sorry, this wasn't what I meant. The slider question is fine, but we wish to use the SUM (Slider 1 + Slider 2 = SUM) value of both sliders as the Maximum answers in the short free text question.

There is 2 questions in the example - Q1 with 2x slider and Q2 multiple short text. We wish to set Q2 to Min answers 1 and Max answers to {Q1:SUM}.

2) Why not use the "Sub-question validation equation:"?

I was asking what the syntax for this would be:

I have tried to change this formula

to this:

And using that code in the sub-question validation instead.

But I get syntax error, and I can't find any info on what the syntax for this would be.

Ah, in that case, I would make the following changes:

• Remove the minimum and maximum settings from the slider question - these are set in the slider settings.
• Place default answers of "1" on the slider question - this helps with relevance in the next step.
• Place relevance on the Q2 subquestions to only show them if the slider sum is above a certain value. For example, the relevance for Q2_3 would be:
  Code:

  sum(Q1_1, Q1_2) > 2

• Use this as the "Sub-question validation equation:" for Q2:
  Code:

  this.relevanceStatus != 1 OR regexMatch('/^([A-Z]{1}\d{1,2})$/', this.NAOK)

This all works well in the attached survey except there seems to be a bug with the "Sub-question validation tip" when sub-question relevance is used - I cannot get it to toggle between the two text values.

Thanks for this Tpartner, working great for me. I was using an old version of limesurvey which didn't have relevance equation on a subquestion level (at least I didn't see it)

Do you know if it's possible to also add a condition to this, to prevent duplicate answers in the multiple short text?

At the moment, someone could potentially enter A1 in all cells - I would like to extend the current code to prevent that if possible.

I've attempted to write/find a regexmatch format for catching duplicates but with no luck

You can use the unique function in the "Question validation equation":
www.limesurvey.org/manual/Expression_Man...#Access_to_Functions

Thanks for the reply tpartner, I mentioned that would like to extend the current setting we have - so we can use the function but we aren't sure of the syntax to use to have multiple functions in the question validation equation (QVE).

Current QVE:

Example of desired QVE:

Is it possible to merge the functions in this way so we keep the existing functionality of regexMatch, but can also force unique responses?

As stated, you need to use unique(self.NAOK) in the "Question validation equation", not in the "Sub-question validation equation". This effectively says "all relevant sub-questions of this question must be unique".
