No, I haven't yet had time to try the method you suggested. I will check it out during the next couple of days I hope.
"Doesn't paste Fred's data; it pastes Merton's".You are correct that Merton is not in my new file.But when I try to copy Fred's data from the old file, it apparently picks up Merton's.When I paste into the new file it brings in Merton's data and since I have Fred highlighted, it tries to merge the two. I do believe that there is probably some relationship error in my file.However, since I have the same problem with other people, I don't think I have proof that it is in the Merton/Fred relationship.
I am going to try a couple of other things.If I have any success, I'll let you know.
