Hi, Michael! Your code indicates that you've assigned the colors array to the listItems variable. If you look inside the html file you'll see an unordered list with the id of "rainbow". The challenge is asking you to assign the collection of list items inside this unordered list to the listItems variable.

let listItems = document.querySelectorAll('#rainbow li');

Here we query the document with the querySelectorAll and pass in the id name we're looking for and the elements inside that id we want to target. This selects all list items within the "rainbow" id.

Hope this helps! :sparkles:
