Mouse Over not working

[AZ_Scott]

Thanks to the v7n for all the help that's got me this far!

I'm not able to get the mouse overs to work within my navbar (http://sans-moi.com/). The "hover" works fine throughout the rest of the website. I think I'm missing some fundamental understanding of how css is working. I've done a couple tutorials but I would really appreciate all your input. You all are the best! Scott
