Help, Website Navigational Issues

Hello,

I created my first website (for myself-- for business purposes). I had downloaded a template and worked with that in Frontpage.

When I clicked "View in Browser" everything looked fine. However, when I did an FTP and uploaded it to the web I have two problems that I think are related somehow, and I cannot figure it out.

1) On Internet Explorer, when I click the navigational buttons, a white flash appears for a second until the page gets loaded.

2) On Firefox, it doesn't do anything at all when you click the navigational buttons.

The website is www.FloridaRestaurantExchange.com

Any help would be greatly appreciated. I'm new at this website thing. I won't be offended if you point out any other major flaws in my coding : )

Thank!!!!!!!
