one problem i see in the source is that the menu is inside of an h2 tag:
<h2>
<ul class="level-0" id="cssmw">
<li><a href="index.html">Home</a></li>
<li><a href="servicesprovided.html">Services Provided</a></li>
<li><a href="7reasons.html">7 Reasons to Call Us</a></li>
<li><a href="specialoffers.html">Special Offers</a></li>
<li><a href="couponsanddiscounts.html">Coupons & Discounts</a></li>
<li><a href="happycustomers.html"> Happy Customers</a></li>
<li><a href="contactus.html">Contact Us</a></li>
</ul>
<script type="text/javascript">if(window.attachEvent) { window.attachEvent("onload", function() { cssmw.intializeMenu('cssmw',{select_current: 0, orientation: 2}); }); } else if(window.addEventListener) { window.addEventListener("load", function() { cssmw.intializeMenu('cssmw',{select_current: 0, orientation: 2}); }, true); }</script>
<br />
<br />
</h2>
remove the h2 tags from around the menu.
