Debug Javascript code on Joomla site

I have created a very simple joomla website. I have added some custom jquery code to animate my menu and buttons. I have installed 2 plugins and i think there is a javascipt conflict somewhere that is making my jquery buttons to fail. I'm not sure exactly where the error is so i want someone to go to the site and find the problem. This is a relatively easy task for someone with javascript debugging skill and shouldn't take you long at all.
