Project not working on web browser

Hey guys,

I did a code-along project using HTML, CSS, and javascript, however the javascript won’t run when I open the project in a web browser. I copied my code to codepen and it seems to work fine, but when I open it in Chrome, Internet explorer etc. it does not work. Any thoughts?

Here is the project
https://codepen.io/jmrtinz15/pen/jRvOwY

Do you get any errors in the console when running it locally?

I did not. Nothing shows up in the console.

Can you post your project on GitHub, so we can see the structure?

I just uploaded it. https://github.com/jmrtinz15?tab=repositories

You are not correctly referencing app.js.

It is working now. Thanks!
