*Author		: Vipin Kumar
*FileName	: Common.js
*Purpose	: Global form validation functions file
*Created	: 07/09/2001
*Revision	: added a dateDiff function
				12/08/2002 : dateDiff - changed the computation of date 
				difference using Math.abs (date1- date2) to
				eval(date2 - date1) - to get tbe actual difference.
				13/12/2002 : fnchangestyle function added to give mouseover effect
