Google Maps Marker Tooltips not working

Not sure why but my google maps tooltips arn't working. To see the page and code please go to http://mdoerrdev.com/bridgeview/region/nearby/ . Click a link to the left to get the Markers to appear. On hover the tooltips should be displaying properly. I've looked over the code for hours now, and I'm not sure what the problem is. Any help is much appreciated

All the code is located http://pastie.org/8174698
