I have a multiple choice question in my survey with the possibility of selecting multiple answers. One of the answer choices is essentially 'none of the above.' It will not make sense if the user selects 'none of the above' plus additional answers. Is there a way to grey out or invalidate the other selected choices if the user chooses 'none of the above?' A screenshot of the question is below.
Alternatively, could an error message appear when the user selects 'none' plus other choices?
!
Thank you!
