Hello,

I have a table with 4 choices and 3 answers possible.

Answers are % of working time in a place.

I would like to limit answers depending on the %.
Exemple:
For answer A1 --> less than 20% the user can select all the answers
For answer A2 --> 30 to 50 % the user can only make 3 answers
For answer A3 --> more than 50% the user can select only 1 answers.

I've tried with unique() key word on question expression, but I don't understand the syntax.

Thank you for your help.

PS: Attache the servey with the question

I would reconsider the question type. Even with those restrictions, you could get a total over 100.

Hello Thanks for the answer.

I know, but it is not really the goal of reaching the 100% it is more find the technical way to achieve this behavior.

In that case, I would think something like this should work (line-breaks inserted for clarity):

It works fine, I do understand a little bit better the syntax.

Turn debug mode on, then click on the configuration menu, you'll find a link to all the EM functions:
