We have an old database of customer numbers that we're trying to steer away from. However, these customers are people who have paid for a membership in the past, and we are still honoring those. So my question is this:
We want to create a form with a checkbox that asks whether or not they have a current membership. If they select "yes" it will trigger a field that requires them to enter their customer number. Is there a way for us to take the complete list of those customer numbers and have the entered value check that list to make sure the number is valid? If it is valid, it will display a green checkmark (or something similar). If it is NOT a valid number, it will display a message to that effect.
Can GF handle this?
