Thickbox Log in Form

Hi everyone, I’m having some trouble with my log in form. I created a thickbox overlay for user to log in through. I followed the tutorial at wpguru.co.za and can’t figure out where I may have inputted the wrong code. The thickbox opens and allows me to enter my user name and password, the issues is the submit button, for some reason the button does not work. You can see what I’m talking about by clicking here. Click Log in in the upper right corner.

Thanks in advance,
Rey
