Miles and Barbara:

Thank both of you VERY MUCH for your insights and suggestions. I now have the invoice detail behaving thanks to you two. EXCEPT: I can't do something as simple as get the Extended column to work. All I want to do is
txtExtended.Value = txtQty.Value * txtCost.Value
However, when I get one line of detail to multiply and Refresh, every txtExtended.Value changes to the new Value, not just the one line I am on. AND, if I arrow up and down the txtQty or txtCost columns of an invoice, lots of strange things happen. Doesn't the pointer in the table move as I move up and down in a grid?? There is something basic about grids that I am missing. This was all so easy to do in DOS . . . .

Again, my sincere appreciation to both of you. Sorry to be such a pest!

John
