You are near. Just use querySelectorAll() method. Hope this help!

Your selector function sets "listItems" to the list element itself. But the instructions say that it should refer to a collection of all list items inside the list.

You can fix this using a different kind of selector, chaining this selector with another one to pick the items, or just by taking the "children" property of the list you're already selecting.
