Hello everyone!

Can i do a matrix, where i can maximize the answers number in this question type --> array (numbers).

I want to a table where I can use checkbox and the maximum answers number is 2(or 3 etc) in every column.

Thx for your help!

Hello, Bogika0107,
please read:
www.limesurvey.org/manual/Expression_Man....27that.27_variables

You find:

What is the total of row B? {sum(self.sq_B.NAOK)}

In your case you want to know the count of the row.

What is the count of row B? {count(self.sq_B.NAOK)}

This way you can set a validation on the rows.

Best regards
Joffm

Dear Joffm!
Thank you for your help. I read the manual and the Expression Manager, but i couldn't fix my problem.
I have been attached a picture. It look like my question now. But i want limit the answers every column (not rows). If i set the maximum number of responses to two -in the other settings-, you can only give two answers in total. But i want you can select the 2 most importat things in every age groups.

OK, I found a solution! Thx
"(sum(self.sq_X1) <= 3) && (sum(self.sq_X2) <= 3) && (sum(self.sq_X3) <= 3) && (sum(self.sq_X4) <= 3) && (sum(self.sq_X5) <= 3)"
