Ok, I looked at it. How do you make a rule that it's not a duplicate? The rule is an expression. I can't think of an expression that would do it.
Thanks,
Michelle

When the user is entering a new record, how do you check to be sure a field doesn't have a duplicate value without moving the record pointer? This also would have to take into account buffering. It seems as though I've done this before, but my head is in a bit of a muddle today and it's not coming to me.
