First off, Cognito forms is awesome.. Amazing tool. I have a club selection and a waiting list selection. I want people to be able to put their name down on the waiting list if there are no places... but not to accidentally add themselves if they've already chosen a club with spaces. Im having trouble getting multiple repeating sections to block duplicate entries from a dropdown. The code Im using works if there is only one option selected. See image - the error comes up. =(WaitingClub.Contains(Form.SelectYourClubOptions.Select(Choice)) If however if add a second entry to the first section, the validation no longer works.
