I am having a problem sorting a mail list by zip code it begins to sort it correctly and then it takes it out of order and begins to resort all over again. There were two lists combined one was exported to an excel spreadsheet from Blackbaud. Anyone with any insight please, please respond my head is about to explode. I believe it has something to do with the formatting but I have tried just about everything I can think of short of retyping....Thanks in advance for help!!!!
