Page Menu has CSS gradient but no hover state?

Please see this test site: http://testsite.marigoldyoga.com

I used Juggledad's colored menu cheat sheet as a starting point and have inserted a css gradient in place of a solid color. I separated the hover state to give it a different appearance, and then put the active state after that. I can't get it to work. Here's my code. Any ideas?

P.S. the gradient code is from a gradient generator I found online.
