I am trying to host my developer profile on GitHub. I have a small javascript typing project I am working on that gets a quote from an API and lets you type the results showing your errors and WPM. It is a little rough right now and certainly needs work but it functions perfectly as is on my local machine. When I uploaded to gitHub though the css and html seemed to have worked fine but the quote and all the javascript functions that load when a new quote is loaded dont seem to work at all.
I am getting the following console error "Uncaught TypeError: Cannot read property 'addEventListener' of null at script.js:16"
I thought the GitHub may be useful aslo https://github.com/nicklandreth73/Nick-Landreth
