In label layout have the "P.O. Box" field override the "Street field"
I am using Filemaker 7 on a iMac with Snow Leopard. I have a mail label layout. Some addresses use a street address, some a P.O. Box. Some have a mailing address in a different town than their residence. (Weird rural system.) Is there a way to have the residential address ignored if there is data in a P.O. Box field or a Mail address field? I'd like to avoid creating a field that duplicates the residential address.
