//		link passed in the value of the option selected
//	HilightCell(CellRef, color1, color2)
//	PlaySound(fileURL) - opens assoc. application to play a sound
//	scrollStatusInit(delay, direction) - uses a variable 'msgStatus' to scroll a message
//		in the status bar
//    parseRSS(RSS Link) - returns HTML string from an RSS feed (IE and FireFox except x-domain)
