Title: La Villa Pizzeria

Purpose: This web application allows a customer to fill out an online pizza order form.

Program Procedures: From a web application, the user should enter their name, address, and phone number. They also should select the size of pizza they would like to order and the toppings. The final cost of the order will be displayed.

Conditions:

1. The website has two pages. The Home page promotes the pizzeria and lists a phone number to call when ordering. The order page displays an order form.

2. The user must be able to enter information to order a pizza using a web form. The user will enter their first and last name address, phone number, the size of the pizza from a DropDownList object and CheckBoxes displaying pizza topping choices (at least six kinds of toppings).

3. After the information is entered, the user taps or clicks the Submit button.

4. The information entered will be validated.

5. The application displays the final cost of the pizza order and a message that pizza will be delivered in under 45 minutes.

Notes:

1. Data validation tools should be used. The first and last names are validated to confirm that they are not left blank.

2. The phone number is checked to ensure that it conforms to a U.S. phone number.

3. Show the Screenshot of the output.
