Please Help: Embedded Flash in HTML

I have read several topics about embedding flash in HTML and I feel that I have chosen the best way to my ability. BUT, it is centered appropriately in Internet Explorer and Safari, but not Firefox.

if you dont want to read my progress in trying to get it centered, just go to bottom
Begin story (ill write it as briefly as possible)

First I used Flash’s built in menu to publish to a 100% by 100% window. This successfully embedded my flash file into html, BUT some users experienced that the flash movie would never launch when I used this method.

I solved this by installing a flash version detection object that I found while browsing this site. I can’t remember its name, but you can probably figure it out by viewing my site’s source code. After following the tutorial, and cutting/pasting code… everything seemed to work EXCEPT…

Now with this flash version detection object, I had to place my code for embedding the flash movie inside of the code of this detector… the code that I used for the 100%x100% fit would not launch the movie at all now. So I reverted back to simply adding the flash movie without any formatting (Insert>Media>Flash Movie). This version worked perfectly in every way, but it would never center in the window. I’ve tried changing the variables in the code to 100% x 100% and changing the alignment tags to center… but none of it had an effect. The closest I got it to be centered with this detector was if the entire movie stretched to fit the screen.

*** End story ***

Would anybody mind checking my source code to see if I have anything that is redundant that may be screwing up the formatting?
