Mark,

We have the similar code in our classes, but I realized, it is not sufficient, since it doesn't check for buffered changes.

Basically, there should be two checks: one in textbox valid (or lostfocus). Another in the save method of the form. If I make this tag to be candidate, the save part would be covered by trapping errors on TableUpdate. I'm thinking, that the best way to check uniqueness on the buffered table is to use COUNT FOR upper(FunName)==upper(m.lcFunName) to lnCheck

If lnCheck>1 && This is a duplicate

AFAIK, COUNT FOR works for buffered table. I think, it would be slow, though.

I should also set deleted off before count and back to original settings after count.

What do you think?
