Problem
We Love Pets is a pet clinic with several locations. The office manager has asked you to create an applet that could run from a browser at all the offices. The applet should be designed with individual check boxes for users to select various services such as office visits, vaccinations, hospitalization, heartworm prevention, boarding, dentistry, x-rays, laboratory work, and prescriptions. As each service is selected, the charge for the service should display. After all selections have been made, the charges should be added together to arrive at a total amount due that displays when the user clicks the Calculate button. The office manager also has requested that when the user clicks the Calculate button, the program will clear all the check boxes for the next user.
