Super confused about this one

I really have no idea what I'm doing. All I know is that adding .children to navigation on line 5 completes task one but task one is no longer passing when on line 14 I add .querySelector("input[type=anchor]");

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 = listItem.querySelector("anchor");
  //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>

The error message is misleading.

:point_right: You overlooked the reminder hint about anchors being "a" elements.

Line 14 should look like this:

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

It's also worth noting that generally when it says Task 1 is no longer passing, it means that you've introduced a syntax error. In this case, it's because there's no "anchor" (that's actually typed that way in tags) element in HTML. Now, you could have a class called anchor (although I'd probably discourage this), but that would be selected as ".anchor".
