You can pass Zip, City, and State CB fields (created by you in CB > Field Management) using database queries in CB Auto Action with a query action. You'd use the after registration and after profile update triggers (frontend and backend). Example query as follows
Code:
UPDATE `#__tablename` SET `zip` = '[cb_zip]', `city` = '[cb_city]', `state` = '[cb_state]' WHERE `user` = '[user_id]'
No idea how geommunity database is setup so you'll need to review exactly how your query should be structured.
