cannot locate the error

I'm trying to make all of my markups valid.  However, xhtml and all the 
other markups are very limited.  So I am writing through php.  I 
validated and got 1 error:
http://validator.w3.org/check?uri=http%3A%2F%2Fcampgroundghosts.com%2FRegister%2Fstep2.php

The source (for your convinience) is 
http://campgroundghosts.com/Register/step2.php
I opened up the source after it was parsed, but could not find the 
problem that it was talking about.

How do I solve this?
