No duplicates for 4 or more subquestions was created by PaulMRFGR

Hi there,

We have a question where respondents must select a price on a scale for each of 8 subquestions. Respondents should be unable to select the same price for 4 or more of the subquestions e.g. they can't select £10 for 4+ of the subquestions.

How can we go about doing this?

Thank you.

What LimeSurvey version?

Can you attach a small sample survey (.lss file) containing only that question?

Cheers,
Tony Partner

For the benefit of others, you are using an array type question with question code "Combinations" and 35 answers with codes 1-35.

In this case, you can use the Expression Manager countif() function to count the number of selections of each answer.

- www.limesurvey.org/manual/Expression_Man...#Access_to_Functions

So, something like this in the question validation equation:

Code:

countif('1', that.Combinations) < 5
AND
countif('2', that.Combinations) < 5
AND
countif('3', that.Combinations) < 5
AND
countif('4', that.Combinations) < 5
AND
...
AND
countif('31', that.Combinations) < 5
AND
countif('32', that.Combinations) < 5
AND
countif('33', that.Combinations) < 5
AND
countif('34', that.Combinations) < 5
AND
countif('35', that.Combinations) < 5

Here is your sample survey back with that change:

Amazing! Thank you - this worked. Just quickly, if we wanted to change it to a maximum of 3 equal answers, how would we change the validation equation here?

Is it just a case of changing the '< 5' to '< 4'?

Again, as a complete novice to coding, I can only apologise for my ignorance.
