Plugin doesn't work on my custom theme

I am having some trouble getting the plugin to work on my website. The script is being displayed in the source but it is not allowing me to view more of my post while scrolling. Here is a link to the page that I am trying to install this on. http://sdfa.finalelements.com/sdfa-labs/ any help will be appreciated.

Thank you
