Operating system: Windows 98

When I am working in PM2000, I can preview my MM1.1 menu all I want. When I upload it to the site (www.adventsoccer.org), It does not work.

This is what I do. I open PM2000, select a page to insert a menu on, select insert MM Navbar, select a template in MM1.1, modify the menu to fit my needs, click save, save graphic, identify the graphics folder, select the html file, it exits to PM2000, I preview the page, publish it to my site (hosted by Netfirms.com), open the site to see if it works, and everything below the point where the menu is insertrd is missing.

Help!!!!!!!!!!!!!!!!!!!!!

I need to know what to do STEP BY STEP to get this menu to work on my site. I am obviously doing something wrong.

Thanks to the angel with the correct answer.
