Limit submission same value on multiple fields

Hi!

I’m trying to limit submissions with " Limit Submissions" add-on. I have a form with 3 different fields for people national IDs (person 1, person 2 and person 3), one person can register 3 different people.

I need to limit those ID to one, they can’t be repeated, but I have them in 3 different fields. I have tried with rule groups with no success.

Any help?

Thanks!

Hello Joruus. I recommend reaching out to the author of the ‘Limit Submissions’ solution you are using. Which one are you using?
