It says: "There was an error with your code: TypeError: 'undefined' is not a function (evaluating 'navigation.children.querySelector("a")')" and I cannot find the bug! Please help

//Select the naviagation

//Select all listItems from the navigation
var listItems = navigation.children.querySelector("a");

//When a navigation link is pressed
var linkListener = function() {

You clearly did well on the first step! But you missed the line in the instructions where it says to put the query selector on line 14. So line 5 should be:

var listItems = navigation.children;

And line 14 should be:

var anchor = listItem.querySelector("a");

Happy coding!

Thank you so much!
