Sandy is very happy with the new Web site you created to promote some of the store's special services. She meets to discuss adding elements to the Web site. She wants to have a way for the user to select from several options for the weekend retreats. The user should be able to enter the type of retreat (two-day or one-day), the number of people that will attend, and whether the use of the store's tools will be needed for the retreat. The page will then display the cost of the retreat based on the selections.
