why is php modifying my html

[glo]

Hi,

I have applied a hack to my main page, but when i rename the file with the php extension and then load it up into the browser, some how the html is not fully displayed as well as the hack not operating at all!

What the page looks like in html can be viewed at www.glo-racing.com/v3/main.html

and the php file can be viewed at the same location but with the php extention ie. www.glo-racing.com/v3/main.php

I have created a test page to test the script which can be found at www.glo-racing.com/v3/test.php which i believe is working correctly!

So I am not sure where the problem is!
