Got it myself. Had to map id, and all of the primary address fields (city, zip, state, add1, add2, add3) and select the overwrite box. When i did it w/o mapping all the address fields those not mapped were written over with blank even though the remaining data was unaffected. Now I need to figure out how to export only those fields required for a mailing!! Uh boy….

Im trying to edit our db to locate people w/blank city and add the city. I was told to use export import. I exported, added the city, now do I only map the id and city for the import? do I check over write (me thinks not) ??

i am in the same boat with my new authorize.net gateway! very frustrating and time suck
