When I converted a 97 database back and front ends to 2000, there seemed to be no problem, at first. Then I noticed problems with code and the occassional expression in a query where there use to be a field! Then I find the field that was there in 97 is not in the table in 2000! I can still add records, but the missing field is an expression in a query, not in the table...which will make new challenges when I try to create new queries. I think some of the code problems are related to the missing fields. Why did it do this? After converting the be, I replicated it and it is being used at 2 sites. How do I straighten this out and get my fields back? I've thought about adding the field back to the table and use the query to run an update.......but then will all the other forms and queries be messed up? Please Help! I'm very worried that I have a mess on my hands.
