I have a form that allows a User - selected first, to then select 8 items individually.

I want to make sure the user never selects the same item twice by adding conditional logic, but I can’t seem to do that on a choice by choice basis per user.

The perfect functionality would be to say if Form already selected X eliminate it from the choices on next selection and so on.

The conditionals only seem to be on the entire table not the form directly.

Any ideas?
