(RESOLVED) W3 XHTML Validator Problem

[GamerMax5]

I went to validate my website in the XHTML Validator on the W3 site and it keeps telling me that my site is "tentatively" valid. Here is what it says afterward:

The document located at <http://gmax5.sky.prohosting.com/MainHome.html> was checked and found to be tentatively valid XHTML 1.0 Transitional. This means that with the use of some fallback or override mechanism, we successfully performed a formal validation using an SGML or XML Parser. In other words, the document would validate as XHTML 1.0 Transitional if you changed the markup to match the changes we have performed automatically, but it will not be valid until you make these changes.

The part where is says the document would be valid if I made the changes it made automatically, how do I find the changes it made so that I can validate my document?
