Bring on the AJAX Not Found The requested URL /sidebar.HTML was not found on this server.

I got that result when I previewed my code on Chrome - I used treehouse workspace.

Here is my code:

var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function(){
      if(xhr.readyState === 4){
        document.getElementById('ajax').innerHTML = xhr.responseText;

What's wrong with my code or why did I get the message that the sibar.html can't be found? Any help would be highly appreciated. Thank you very much in advance.

I am sorry for posting question, I just found out that I wrote HTML using upper case, and changing it to lower case solved the problem, once again sorry...
