JavaScript AJAX Basics (retiring) Programming AJAX Check for the correct ready state

Why won't it accept my answer?

Challenge: Use a DOM element's innerHTML property to set the HTML inside the sidebar div to the server's response code challenge?

The error message keeps telling me to insert code that is already there.

I'm so confused.

app.js 
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
  if (xhr.readyState === 4 && xhr.status === 200) {
    document.getElementById('sidebar').innerHTML=xhr.response.Text;
  }
};
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>AJAX with JavaScript</title>
  <script src="app.js"></script>
</head>
<body>
  <div id="main">
    <h1>AJAX!</h1>
  </div>
  <div id="sidebar"></div>
</body>
</html>

Hi Ja'Nel

You pretty much have it, but you put a period between 'response' and 'Text.' It is just one word - 'responseText' Once that's fixed, you're all good. :)

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
  if (xhr.readyState === 4 && xhr.status === 200) {
    document.getElementById('sidebar').innerHTML=xhr.responseText; //removed period
  }
};
