Php include trouble

Hello,

I’m trying to use php include to load content into a template page, so that the template page is all that needs to change for a site-wide update. However, the index.php page, or the include in the template page, does not seem to be set up correctly, since it cuts off everything after the php include and does not load the content.

Essentially, the site will hopefully be a 2 column, left side navigation, with a header and footer.

The template is just a skeleton until everything works, but you can take a look at the results so far here: http://polymaze.funformentals.com/PHPtest/

Here is a link to a rar containing the files:

This is the first attempt at making a site this way I have tried and would really appreciate any help or tips on fixing the problem.

Thanks
