Your LimeSurvey version:  Version 5.2.13+220207
==================
I have this question where I want the first column to be selected only by one of the options (1, 2 or 3). I tried with unique(self) but this makes all of the columns unique and it does not allow me to move in the other page even when the 3 options have different columns selected. 

Can someone help me solve this?

Thank you in advance!

Thank you for your reply! This works fine on my previous .lss but I have an array filter at my full survey and it does not seem to work in that case.

What could I do?

Thank you Joffm,

I am not figuring out what should I change, I tried some ways but none of them seem to work. count(G02Q14_AO01.NAOK) <= 1

If it is not much trouble for you could you send me how you did yours on your screenshot? If not, still thank you for your time.

That is not close to what I suggested. Joffm is just suggesting appending NAOK.

Thank you again.

I tried this one too but there is something wrong. Still thank you and I will try to figure it out on my own now.
