I have been struggling with mail merge 2003. My database is in excel and is a compilation of two different lists, one purchased and one personal. Publisher deleted the leading zeros, until I formatted the list as a csv file. Then, after only 4-5 printed pieces, the printer (Okidat 5200n) gives me a fatal error 073 which the Oki people tell me has to do with the program I'm using.
I went back to regular excel fomatting and forced in a zero once mail merge was open, and can now print 20-25 pieces before I get the same error message.
