I'm working on a site for a customer, and I'm having problems with my horizontal menu ... I've been successful in making everything fluid so that no matter what browser one uses, it scales appropriately.

However, in IE, the horizontal menu is centered ... though I would have liked it to be the same width as the banner in the header, but I can live with it not being th same width ...

Now, in Firefox, the horizontal menu is not centered ... it's at the left and no matter what I've tried, it won't budge from the left hand position ...

Does somebody know a way that I can get this menu to center and still remain fluid and standards compliant?

Thanks in advance for your help ...

Here is the template, so you can see what I'm talking about ...
