I've checked your site's homepage, and it appears you have a jumble of different types of GA tracking code inserted there. Up in your page HEAD, you have a block of GA's new Universal Analytics code, then down towards the end of the page, you have only part of our recommended GA code, plus another section of the much older urchin.js GA code below that.
Those 3 versions of the GA code will all conflict with each other. so make sure you're using ONLY our custom version of the GA code on every page where you want to use GA tracking at all. Do not mix'n'match our code with any other GA code from Google, neither on the same page nor across different pages of your site. Here is our version of the code that you'd need to use (replace the "UA-XXXXX-X" with your own ID string for GA):
var ejGATracker = gat.getTracker("UA-XXXXX-X");
