I I have two questions. The first is single choice (G01Q01) and second is multiple choice (G01Q02). The goal is to hide subquestion in the second question based on the answer to the first question. In the attached example, subquestion 1 (SQ01) should be hidden if the answer to question 1 is not the first choice (AO01).

My solution was to add (G01Q01.NAOK == "AO01") in the condition box of SQ01. It did hide the first subquestion of G01Q02 unless the first choice is selected in G01Q01. However, the survey cannot be submitted unless the first choice is selected in G01Q01(See pictures below). The survey example is attached. Any suggestions?

Hi,
you attached a lsq export; please attach a lss export.

lsg (group) and lsq (question) exports are language sensitive and don't contain the other settings of your survey.

Joffm

And in the LSS export only include the questions that are relevant for this issue, not the whole questionnaire.

But from what I see, your survey is exactly doing what you want. Not sure where the actual problem is. Is it this part?

However, the survey cannot be submitted unless the first choice is selected in G01Q01

Could you explain a little bit more, what you mean with that?

Sorry about that. Just uploaded the lss export.

Here is the problem. As shown in the screenshot, when option 2 was selected (in fact, any choice other than option 1), the error message "One or more questions have not been answered in a valid manner. You cannot proceed until these answers are valid." popped up, preventing the survey from moving to the next page or, in this case, being submitted.

I can confirm this behavior, but I can currently not explain it. Tried a couple of things to get rid of it, but without success. Need to check deeper, might be a bug.

byan, please file a bug report.

Submitted. ID: 16084 under the "Conditions" category. Thanks!
