> oldformname.propertyname.fieldname

I knew, this idea (using form's property) would work, but haven't advised it, because the standard and well recommended way is to use table buffering instead. Anyway, as long as it works for you, it could be used...

Claudio's original approach should not work, I even don't need to try. However, Jim Booth indicated, what it worked in VFP7, so we need to find out, why...
If it's not broken, fix it until it is.
