Why does SWFObject work in chrome yet not IE/FF? (example included)

Am I using the code improperly or is there a flaw in SWFObject? If you go to the URL below you can see that it the flash file (an MP3 player) shows up perfectly fine in Chrome. However, in both Firefox and IE8 it loads a blank white box. If you mouse over the box the pointer changes to a hand as if its registering the buttons, j开发者_如何学JAVAust not actually displaying them.

(MP3 player should be displaying in the right-hand empty column)

I get the player (flash) in Firefox 3.6.10. Chrome has a built-in flash plugin. IE and Firefox haven't. Get Flash Player from http://get.adobe.com/flashplayer/
