I have several feature classes I'm trying to merge together. I have done this several times and get some thing different every time. I was looking the attributes and some have been changed to 0,merged into the same column, or just not there. I am working in Arc10 but one of my co-workers is working in 9.3 and is havin gthe same trouble.
