    pizza.htmlI am looking for an example so tha I can complete an assignment in a client and server side scripting class that I am taking. I need to be able to add totals of the prices of the check boxes and radio buttons on this page and display the results. The part that is completed is from the W3schools tutorial. I need to finish this so I can move onto a php assignment.
