Dear all
I'm a newbie so apologies in advance for the nativity of my question. I have a question in my survey which is a matrix table using a 5-point Likert scale (1 = Would never use; 5 = Would always use). Each item refers to a psychological treatment that a clinician might use, but of course my list isn't exhaustive. For this reason I have included three items with text boxes so that participants can nominate any other treatments that they might use. I would like this question to be forced choice, except for the free text items. I have looked through community responses and found a solution, but I just can't seem to make it work. That solution involves creating customised validation in the form shown below. When I complete the survey in Preview mode, however, the custom validation does almost nothing (it will force a response if some items have not been completed, but not others). I would be grateful if anyone can point me in the right direction. The images below are my original question, and then my customised validation logic (you can't seen all the custom validation, but the logic should be clear).
