It's more complicated than I thought. The unit price above is not $.20/print, it's $.20/sq foot. So to get the extended price, they have to multiply the # of prints times the unit sq footage/print (which equals the total sq feet) and then times the unit price.

I can get to the correct extended price by using the Price Adjustment field, entering the number of sq feet as the "adjustment factor"). But I can't get the total sq feet to print, unless I also have them put the number of sq feet in the Cost field as I mentioned above. It's bad enough that the field labels don't match the contents, but to have them double-enter the number of sq feet is even worse.

I love being able to tell users that Invoices can work for almost any kind of invoice - I hope I haven't met my match.
