I have 4 questions (4 fields) in a form. 2 are drop down menu type and 2 are open text fields.
I would like to limit the user from entering data in the fields if one has been answered.
for example:
if Question one is answered, question 2, 3 and 4 should be locked and should not allow the users to fill in anything.
How do I create that Locking system?
Thanks,
