This is the fisrt part of the FAQ page:

<div class="centerColumn" id="faq">
<h1 id="faqHeading">Frequently Asked Questions</h1>


You used the same id (faq) for your image map, and positioned it with:

#faq {
float:left;
position:absolute;
width: 100px;
height: 70px;
margin-left:682px;
margin-top:167px;
}

so the stylesheet is applying the same positioning to the page header.

You'll need to rename that id in your image map.
