CSS Centering Problemo

[Deathwish]

Decided to renew my face on the Internet but have come across a small problem that I can't seem to figure oot.

The menu bar is centered in IE6Win but in FireFox its not.

The CSS is included inside the HTML document for now, will be moved into its own file once i've finished up the design.

Any clues as to why are appreciated

Ah, spot on Beansprout, did not notice that. Strange how you can miss things in your own code, yet spot them fine in someone else's!

Thanks
