Friends, I need some help. I'm creating a registration form that, as soon as I type a postal code and press enter, needs to consume a PL/SQL instruction. If everything is correct in the programming, it should display more filled fields on the screen. I need to know if anyone has done this before and if there's a way to test the number of digits being entered on the screen. If it equals 8, then the system should enter the form's dynamic action, execute the code, and populate the fields that need to be populated.
