Hey pratyush raj,

Your code is correct but you need to include the open method outside the code of block.

Here's the code:

var request = new XMLHttpRequest();
request.onreadystatechange = function () {
  if (request.readyState === 4) {
    document.getElementById("footer").innerHTML = request.responseText;
  }
};

request.open('GET', 'footer.html');

Hope this helps!
