JS Twitter Feeder Not Working

I'm trying to add a twitter feed to my website and don't seem to be having any luck getting it to work. This is my first experience using javascript so I think perhaps I'm missing something obvious (?).

The test website is: [url]

I followed these directions from a blog:[url]

Put the JS code referenced inside the header tag, made the corrections to system.js (basically just changed the name of the user, and asked it to search "fromUser" instead of "searchWord"

Also put the div instructions in my CSS and the code listed on my page.

Am I supposed to put anything inside the div container? (Stupid question I know but I'm stumped).

Here's the relevant code from the blogsite:

Code:

HEADER TAG CODE:

SYSTEM.JS CODE:

BODY CODE (inside div#left container where I want tweets displayed):

I uploaded the js folder to the directory where I am testing this page. Do I perhaps have it in the wrong area? Should it be in the public_html directory instead?
