Please help... File won't open

I'm using cck filefield to upload an html file from my server. The html file refers to an swf file, an xml file, and a js file. Everything is working fine, except that when I put the block on my site, it displays the name of the file, rather than the html content. When I click the hyperlink displayed in the block, it opens the html file in a new window without any theme, etc. I want to be able to view the html file in the block on my site.

You can see it not working on my site:

The block is called Map and the html file is map.html

Thanks!
