jQuery won't run on development site, but works on online code editors.
Can't find conflict

I am having an issue with jQuery where I can get it to work on different
testing environments, but not on my development site. I can't seem to find
the conflict or what would be causing it.
How it should work: When you hover over the icons, it changes the visible
div above. I have it working here:

I can't get it to work on my development site here (where I want it):
http://talemetry.redbranchmedia.com/
I also set it up on a test page because I thought maybe the slider was
interfering: http://talemetry.redbranchmedia.com/testing-page/
Unfortunately, it isn't working anywhere on the development site, but it
is working on the JSFiddle and CodePen sites.
I've tried numerous things including: Calling different versions of jQuery
from the Google Developer Libraries Calling in jQuery internally on the
site Replacing the " $ " in my script with "jQuery" (the theme authors
seem to have done this) and much, much more.
I'm at a loss for what's causing the conflict and preventing this from
running. I appreciate any help.
