Cetin,

BoundTo is .T. (tried it with .F. too)
Valid is a user procedure that goes somthing like this:
SELECT extras (this is the grid table)
REPLACE extras.Labor WITH This.text
SELECT laborate
LOCATE FOR laborate.labor = extras.labor
IF FOUND()
REPLACE extras.lab_price WITH laborate.retail, ;
extras.lab_cost WITH laborate.wholesale
ELSE
MessageBox("Sorry - not found.")
ENDIF

A lot of detail is left out of this example, but the main ideas are here. I also refresh the adjoining columns of the grid, for instance.

Thanks!
Tom.
