Hi Carol,
While I don't think this is going to be much help - I thought it would still be nice to get a reply :-)
I tested your scenario and it works fine for me. The only comments I have are:
<> Are you sure that the field chosen is really "Qty On Hand" and not "Qty on Hand 1" or one of the other 4 quantity on hand fields that may be around when using the FIFO or LIFO costing methods ?
<> Have you tested on Sample Data ? Does the Sample Data have the same problem ?
