... My friend, did you check your resources? You are getting an error on the second page because you are accessing your Main.js from relative paths in your template.
jatecson.com/information : http://jatecson.com/js/Main.js
Load that file and yay! We've loaded your JavaScript file.
jatecson.com/set/images : http://jatecson.com/set/js/Main.js
Load that file ... and... hrmmm. That doesn't seem right...
You must be loading resources with a relative path in that template, when you should be using the {site_url} variable to direct your resources to absolute paths.
Here is your code to load that JavaScript file:
<script type="text/javascript" src="js/Main.js"></script>
You are loading from a relative path! So when your URI is / (base site root), you get http://jatecson.com/js/Main.js. But when your URI is /set/, you're getting http://jatecson.com/set/js/Main.js. This is true of all of your resource tags. If these are ExpressionEngine parsed templates, you should use the {site_url} path like so:
<script type="text/javascript" src="{site_url}js/Main.js"></script>
You might need to add a / after {site_url}, depending on what it's set at.
If these aren't ExpressionEngine templates and actual flat static served files, you'll need to edit them and manually add your domain to those src parameters.
