when php extension is used, the code gets modified!

[glo]

Would it be possible for you to have a look at
www.glo-racing.com/v3/main.html
and view the source code. It is also the code for
www.glo-racing.com/v3/main.php
corrupts the code.

I dont know why it is doing this at all. The html code is fine because it all work in the .html file except for the php parts,

Wehre as in main.php the page is only partially shown and i cant even see any php script being active on the page!

Your help is greatly appreciated.
