I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Use This script
var basicRoomCost = 20;

	var numStandard = document.getElementsByName('standardroom')[0].value;
	var numExecutive = document.getElementsByName('executiveroom')[0].value;
