R 'n R has decided to start selling books online. Create a web site to calculate the amount due, including discounts. Allow the user to display the total of the discounts. The user enters the quantity, title, and price of a book, and the program calculates the extended price, a 15 percent discount, and the discounted price. The input must be validated. The quantity and price are required fields, and the quantity must be an integer between 1 and 100. Additionally, the program will maintain a total of all discounts given and display that total on the page in response to a button cick. Include a second page for contact information..

Here is how it should look.
