I'm trying to figure out a formula for the following. I
have an order form where certain products are classified
as one of two categories. THe two categories exist in a
combo box control (not userform or vba). I want o add up
the category total for cat1 and total for cat 2 items and
based on the sums, calculate a delivery and install fee.
Basically, if i have this much worth of cat1 items, charge
this much D&I, if ihave this much, then.........and so
forth. I have everything except how to include the combo
box in the formula. Can anyone help?

thanks,
