Task 1 no longer passing

Whenever i try to complete task 2, the message says that task 1 no longer passes. I didnt change anything in code for task 1. Help!

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

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

//When a navigation link is pressed
var linkListener = function() {
  console.log("Listener is clicked!");
}

var bindEventsToLinks = function(listItem) {
  //Select the anchor
  var anchor = listItems.querySelector("a");
  //Bind the linkListener to the anchor element (a) 
  anchor.onclick = linkListener;
}

for(var i = 0; i < listItems.length ; i++) {
    bindEventsToLinks(listItems[i]);
}
index.html 
<!DOCTYPE html>
<html>
<head></head>
<body>

<ul id="navigation">
  <li>
    <a href="#home">Home</a>
  </li>
  <li>
    <a href="#about">About</a>
  </li>
  <li>    
    <a href="#contact">Contact</a>
  </li>
</ul>

:point_right: It looks like you just have a typo.

You spelled listItem as a plural (you have "listItems" with an extra "s").

This caused an error when the script attempted to access the method querySelector on an undefined object. Since the error invalidates the entire program, and the checker re-tests task 1 first, it mistakenly assumed something had gone wrong with task 1.
