Here is the site

www.advancedroofingnewyork.com

the navigation buttons behaved properly when I tested them in a browser, but when I uploaded the site, they work right until the "onmouseout" comes into play, and then it leaves no image at all...

here is the portion of the code that tells the buttons how to behave...see anything obvious here?

id=bv01007 onmouseover="SwapImage(1,0,'bv01007','bv01007_over.gif')"
title="Advanced Roofing and Contracting carpentry services"
onmouseout="SwapImage(0,0,'bv01007','bv01007.gif')

Thanks in advance

Yikes, no ideas??
