XHRHttpRequest Not Updating My HTML

Hi guys,

I can't seem to reproduce the result that Dave has in this video. I've pored over my code and I can't see any error, but when I try previewing it nothing happens.

I opened the JavaScript console in Chrome and checked the Log XMLHttpRequests which shows "XHR finished loading".

The only issue that I can think of is the log is showing a different URL for the "GET" request to that which is showing in my workspace. i.e., it shows the URL of the preview window with "/sidebar.html" appended, rather than the URL of the workspace which is housing my files.

My code snippet is here: https://w.trhou.se/7qoff3cu6v

Any help would be greatly appreciated.

Cheers Don :-)

// Line 12
if (xhr.readyState == 4) {

// The S in State has to be capitalized

// xhr.readystate - invalid
