What is the problem? Please be detailed.

Let say one of my questions is like this:

  1. what is your favourite movie? -> multiple answers/can choose more than one
    answer: A. avenger B. batman C. superman D. james bond E. Cartoon

And the next question is:
2. which one does make you angry for a week? -> just select one answer.

The second question will appear if they choose more than one answer in the previous one. If only one answer, this question will not appear. How can I make this command in the column "relevant"?

Thanks!

Hi @danielhombing

you need to use relevant + choice_filter
I prepared an example for you:

I'd probably suggest using count-selected(...) in your relevant calculation; eg

count-selected(${your_multi_select_question}) > 1
