Multiple Image maps in WordPress site are not functioning

Hello, I am a novice developer, and seem to have broken my site. I am attempting to use multiple image maps for navigation in the site (for visual reasons), but if there is more than one image map, the links for one (header nav) get applied to the other maps! I am building them in Dreamweaver and pasting into various parts of the WordPress site. My site is viewable at http://www.chugthebug.com/wordpress. For instance, the footer image is supposed to contain links, but the header nav seems to have broken the footer image map. Any help is greatly appreciated, I am a novice!
