Adding product to the cart in Market Press

We are using Market Press for a simple e-commerce solution. Our organization sells seats to classes. We set up an inventory item, and display ONLY the add to cart option on the info page. We use Formidable Forms on the site. What I need to do is to get info from the user - name and email, before they can add the class to the cart. Is there a way to embed code in the form to add the product the user picks when they Submit the form?
