I wonder how I can check on not allowed combinations of select_multiple answers.
For example: I have a list of multiple choices (category): none, covered, uncovered, vip. If none is checked, the others should not be applicable, for the others any combination is possible. It seems awkward to list all possible combinations as a constraint.
I was thinking of something like if(selected(${category},'None') then count(${category}) has to be 1 but how do I put this as a constraint?
Thanks in advance!
Hi Nicole
Great idea for the constraint. A similar query came up on GeoNet recently - the constraint syntax below might be of use? (With thanks to James Tedrick.)
Cheers,
