Actually, I suspect you'll want to be able to have the total price
recalculated when 1) the component is changed or 2) the quantity is
changed, AND both fields have an entry.
One approach would be to write a general procedure as "code behind form" --
this procedure would recalculate and fill the total field, based on the
contents. In each of the two other fields' (quantity, component)
AfterUpdate events, you'd "Call" that general routine.

Good luck
