Validating one custom field against another

I would like to have an entry for number of adults and then follow it by asking how many of those qualify for concession rate, so is it possible to make sure that the number entered in to the concession field is less than or equal to the number entered in to the number of adults?

Hi

Unfortunately, it is not possible. We don't have a way to perform that validation in Events Booking at the moment

ok, thanks - hope it might be added one day
