Take a look around the html and js files. Line 5 of app.js is incorrect. listItems should be the children of the naviga

Lines 1 through 5 of app.js currently have the following code:

//Select the navigation
var navigation = document.getElementById("navigation");

//Select all listItems from the navigation
var listItems = navigation;

If you look at index.html, it has an unordered list (ul tag) with the id of navigation. So the navigation variable will refer to the ul element.

listItems is currently just referencing the navigation variable, so it will just be assigned the same ul element, when it should be referencing the li elements that are child elements of the ul.

So you need to use the children property to access the child elements. In this case, you want the children of navigation.

I'll leave it to you to figure out what to write on line 5. :)
