Converting state address field into two letter abbreviation

Thanks. I am using the standard Address field. The problem with Solution #1 is that when you search for an address, and select one from the auto-suggestions (a very handy feature), the state field is left blank. Quickbase seems to require that the state options be the complete, spelled-out version of the state names in order for this to work. I guess if I like that feature enough I'm forced to do option 2.
