I just looked at your page, and the problem is that you don't have any Application ID set on that page. You need to have a Facebook application set in order to let users register for that application, and your site.
For more information on how to create the application, see:
www.sourcecoast.com/jfbconnect/docs/configuration-guide
Once created, make sure you use the settings in the Facebook API Configuration tab.
Hope this helps, and good luck!
