The link in your post goes to a page with a 900x800 pixel image map on it. There is no script. If you are using this script then, using a text editor, you can put it just before the last closing division tag:
</div>
on the page and add two more </div> tags after that. Change this part of the script's markup:
HTML Code:
<div id="scroll3" style="width:170px;height:150px;background-color:lightyellow;overflow:scroll">
to this:
HTML Code:
<div style="position:absolute;top:300px;">
<div style="position:relative;right:300px;">
<div id="scroll3" style="width:600px;height:150px;background-color:lightyellow;overflow:auto;">
