Narad,

>I would like to know of a procedure to enter data into fields and tab to get a subtotal then a total i.e. I am trying to multiply quantity by price to get a subtotal then I have this subtotal summed to a grand total.

In the LostFocus() of txtQuantity and txtPrice:

thisform.Refresh()

In the txtSubtotal.Refresh():

*assuming txtQuantity and txtPrice are bound to the fields quantity and price
this.Value = quantity * price
