SWFObject problems

Asked about this before but it never got solved… it seems that when i use this code it only shows a white(blank) page if i have an earlier version of flash player installed… works fine if there is no flashplayer at all(alternative content shows) or if flashplayer 10 is installed (shows flash contents). I need it to show alternative content if visitor have earlier versions of flash player…

ty!
