Question is multi-select with NA/question
I have 3 questions:
1. Can I make the other checkboxes un-check when the N/A is checked?
2. I want the respondent to have to check either the N/A box, or between 1 and 3 of the multi-select boxes. Is this possible?
3. When the page advances and then I hit the back button, the multi-select boxes are grayed out and cannot be checked, but I want them to be able to change their answer. Can this be fixed?
