hi i am have 2 forms 1 for  user registration and the other for  service requests but they both base on generated receipt numbers. now am trying to prevent users from using the same receipt  to apply for another request from the second form. i need a way make the receipt number usable once. for instance if you use the receipt user registration, you cannot use it again for service request.

Did you try making the field unique on the forms?

yes i did. but the issue is that since there r two forms the use can still use the same receipt on the other form. using the receipt on the same for again does not work but it works with the second. that is what i want to prevent.

Make the field unique on both forms.
