Epic editor

I am having some issues with the JS for the Epic Editor function.  I will add notes on follow up comments to specific lines in relation to the Epic Editor QuickStart guide (http://epiceditor.com/)

Also, currently I am receiving an error when I troubleshoot in the developer tools.  The console error says:
Uncaught TypeError: Cannot read property 'webkitRequestFullScreen' of null         epiceditor.js?body=1:531
EpicEditor.load                              epiceditor.js?body=1:531
(anonymous function)                   application.js?body=1:19
