How to prevent duplicate answers on a field?

Hi

In my form I have asked for an email address as well as an alternative email address in two separate address fields.

I need to set up the form to ensure that the same email address is not in both fields.

Is there a way I can require a different email address in the alternative email address field?

You may use conditions to compare the email address field and if they are the same you can add an error message or hide the submit button.

Sample condition to compare fields.
