The form asks for all the pertinent information about the pizza: the pizza base, the base sauce, and the calculates the price. A customer may order as many pizza's as desired.

People who want to buy pizza's come to the site and search for the pizza's they want. When they decide to buy, they must open an account with a credit card to pay for the pizza's. The system maintains all this information on secure servers.
