I've come across a dilemma in which I am needing help. I am wanting a text field to be required after a relevant expression has been assigned. For instance, I am wanting the user to choose a 'yes' or 'no' value asking whether or not they want to apply an e-mail address to the survey. If the user chooses 'yes', the e-mail address text field is made visible and is required. If the user chooses 'no', an input box is simply disregarded (the way a relevant expression should work).
The problem I'm having is that if the user chooses 'no' and tries to submit the survey, a Required message appears (which I assigned in the appropriate column) asking the user to put in a valid e-mail address even though the option to type in an email address is not present because of the relevant expression. Is it possible to have a required text field only be required if the relevant expression holds true?
