Grid has recordsource and you task is actually counting values within this cursor or table, e.g. you may have some form.getttoal method:
Select SUM(qty*price) from mycursor into array myarray
Thisform.Mytextbox.value=myarray[1]
and call this method from any places where user may change either qty or price: e.g. Grid.Column.txtQty.InteractiveChange event
