Hey William Domenech 👋

You'll want to have a close look at how you're trying to select the li elements. Currently you're calling a documentElementsByTagName function which does not exist.

Instead you'll want to use the getElementsByTagName method which you can access through the document object: 

let listItems = document.getElementsByTagName('li');

Hope this helps! 🙂
