Custom overlay map with clickable off/on layers

[justawebbie]

Hi, I seem to have something not quite yet in my map.  I combined my maptiler images and 2 fusion table layers onto a google map.  The problem I am having is the toggling between my fusion table layes is not working.  I would like the Campus markers to load then if you want to see the Sustainability ones you can click Campus off and turn on Sustainability.  Plus the center is not center like it should to.

You should be able to formulate a solution from the attached code, which uses a select box instead of checkboxes.  The reference which I used to implement the page was found here. Good luck,
