I have been constructing this Office 2000 Access database for about a year and a half for the company that I am working for. It is replicated and all users save me work on the replication. Recently, it has started coming up with, in only certain instances, a "Data Has Changed" error when I try to get it to assign values to certain on screen controls that weren't triggered before--I have not changed the code underlying these area since before the errors started. Compacting and repairing does not get rid of this error, neither does importing everything into a fresh database. I am hoping that someone out there has a clue what to do about this. Please help!
