Not 100% sure if this is the cause, but there are a few small html problems with your ul li list...
you have
Code:
<li><a class-="nohref">Governance</a>
Note the "-" before the "=" sign
also, I notice:
Code:
<li><a class="nohref"">Outstanding Achievement</a>
you have an extra closing quote.
Finally, and this might be the issue here...
You're missing a closing font tag in your html content...
Code:
<div style="margin-left:9em;height:20em;">
<img src="header1.jpg" align="top"><p>
<h1><font color="maroon">
Welcome Back to the 2007 - 2008 School Year!!
</h1></font>
<font color="maroon">
Classess resume Thursday, August 30, 2007 for all students.
<!-- Need closing font tag here -->
</div>
