	Purpose:	Functions to create and validate 
				custom forms.  Can be used on almost 
				any page but mainly:  
				- displayEventInfo.html 
				- displayItemInfo 
				- displayNewApp/srComponents
	Version Notes:
				3/30/07 - Updated checkCustomForm 
				function so that the results are 
				passed on differently depending 
				on where the form is used.
				
				5/31/07 - Cleaned up label of 
				' and " characters for 
				alert function.
