Hi how do I stop people choosing an option they have previously chosen?
Answer
Dropdown repeated answers
Best answer by john.desborough
it took a while for me to get to the drop downs but here is how you might want to consider the restriction - this is just a suggestion and there are likely more elegant solutions but ..
- Assume that the first dropdown question is question D1 (for ease of number)
- user selects a choice from D1 and goes to D2
- user selects a choice from D2 and you use logic to determine if D1 and D2 are both the same selection
- if D1 = a1 AND D2=a1, then go to a statement page that says you already chose that one, please go back and choose another (repeat logic for all other choices in the list)
- the statement page takes you back to D2
- when user has two unique choices, let them go to D3
- select choice
- If D3 =a1 AND D2=a1, then jump to another statement page that says you made a duplicate choice - go back to D3
- if D3=a1 AND D1=a1, then ditto
i created a little demo here and is the logic flow diagram for that

hope this helps
