I have an Order form with two Paypal Multiple Products drop down boxes. These total correctly in a Paypal total field and hand off to Paypal, send user emails etc.

However because I have a choice of two items I have to offer a zero quantity of each, for people who only want one of the items. This means that the form can produce a zero order. How do I trap zero orders and require users to select at least one item so that the Paypal total is greater than zero?
