Hi all,
I've looked through the threads on this topic carefully but they don't exactly cover my problem so posting here.
So I have a multiple select question (what other crops did you cultivate?). The answer option is long, but the first option is "no other crops". I would like to add a constraint that if you select this first option, then you cannot select any other.
I've tried this but it is not working:
(not(selected(.,'1')) and count-selected(.) >= 1) or (selected(.,'1') and count-selected(.) = 1)
the answer option list is super long, and the respondent can select as many of the other choices as needed, typing out a constraint that fits all combinations is too much (i.e. I would not like to use something like (not(selected(.,'1') and selected(.,'2')) or (not(selected(.,'1') and selected(.,'2') and selected(.,'3'))....the list goes on for 100 possibilities.
Unfortunately we cannot create an entry yes/no question either for unrelated reasons, though i know that'd be the fastest way.
Any colourful solutions? Many thanks.
