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.

The second image shows two clubs added. It submits! But football already chosen Problem.
