Ajax Callbacks Code Challenge 4 of 4

I'm not sure why I can't pass this Code Challenge. This code works on the preview but it won't let me pass.

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(data) {
  if (xhr.readyState === 4){
    document.getElementById('sidebar').innerHTML = xhr.responseText;
  } else if (xhr.status === 200){}
xhr.open('GET', 'sidebar.html');

Hi Stephen Spears

You don't need an else if clause. You should have both the readyState`` check AND thestatuscheck in the same conditional statement. Use&&``` to test that two conditions are both correct:

if (xhr.readyState === 4 && xhr.status === 200)
