// MODIFICATION LOG:
// DATE        AUTHOR		VERSION		MODIFICATION
// ====        ======		=======		============
// 01/14/2005	dp			1.0			Initial Generation
// 02/01/2005	dp			1.1			Changed the IF statement *1
// 04/15/2005	dp			1.2			Added an alternate promotion *2
// 05/25/2005	tb			1.3			Added a start date to promotions *3
// 10/2/2006	es			1.4			Added banner rotation
//
// USE:
//		Built for Ala Moana Center to automate switching out the Flash movies on the
// 		homepage. These Flash movies contain promotions that end on certain dates and
//		need to be switched out at inconvenient times.
//
// *1	The IF statement was changed from '(theDay < expireDay)' to '(now < expireDate)'
//		The previous statement only accounted for the day which didn't function properly
//		once the next month came along.
//
// *2	The purpose of the altpromo is to run back to back promotions. The first promotion
// 		will end, then the alternate promotion will begin.
// 		NOTE: Should be rewritten to be more flexible and interchangeable. The code will
// 		look for promo 1 first. If that is expired it will move on to the alt promo, then
// 		to the default promo. Promo 1 and alt promo should be interchangeable based on date
// 		of promo.
//
// *3	Start date variables were added to so that the promotion banner can be set to automatically go live.
//		The IF statement was changed from '(now < expireDate)' to '((now > startDate) && (now < expireDate))'.
//		The changes were also made to the alternate promotion.
//
// *4	If both banners are set to run, banners will be randomly displayed in first IF statement.
