I'm working overtime after normal hours to do some work on my company's website. After beginning to work on it yesterday I was thinking about where I'm heading with the site and have a question about something I have never done before.

My company produces portraits for college students. I'm in charge of adding a form to the site so they can order, and pay, online. The only issue is I have no idea how to create a form so that when one or more of the 13 different print options are selected the total due in PayPal will be correct.

Say a student orders a Bronze package and an extra 5x7.

How would I set it up so that when advancing to PayPal to pay the amount due represents a bronze package and 5x7?
