// Handleform that allows for up to two drop down menus and an additional checkbox style
// item.  The names of these form elements should be as follows:
// 		- menu1: the first drop down menu
//		- menu2 (optional): the second drop down menu
//		- optionalAdd (optional): the first checkbox offering a product addon
//		- optionalItem (optional): a hidden element storing the SKU for the first optional addon
//		- optionalAdd2 (optional): see optionalAdd
//		- optionalItem2 (optional): see optionalItem
//		- optionalAdd3 (optional): see optionalAdd
//		- optionalItem3 (optional): see optionalItem
//		- ProdList: a hidden variable that will eventually serve as the list of products the user
//					has selected from this page.

//7/16/07 Mod Ron Clabo - Modified the code to use prodListStr rather thatn ProdId and also added
//                        code to alert the user if they haven't selected an item in the drop downs
//                        rather than to have them go to an error page.  Also simplified code.
