>The RecordSource for a grid is a table. The Table contains severl fields that hold codes which don't have meaning to the end user.

John,
In an editable grid any calculated column is readonly by default and cannot be made editable. For calculated columns generally it's extra parentheses that make it work. ie: For orders table you could have a form method calculating net value based on amount, discount and tax percentage :

NetColumn.controlsource = ;
'thisform.calcval(orders.order_amt,orders.order_dsc,10)'

would work. However making it :
NetColumn.controlsource = ;
'(thisform.calcval(orders.order_amt,orders.order_dsc,10))'

is more reliable.
