Ajax simple lesson not working for me. What am I doing wrong?

Wouldn't hurt to zoom in the example videos a bit.. Squinting isn't much fun lol. Otherwise, I've been up and down this trying to type it out to follow along. Button doesn't work for me.. I'm using the workspace for this. Just wondering what I did, or if it's something server side. I'm just trying to type what you typed.

<script> var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function() { if (xhr.readyState === 4) { document.getElementById('ajax').innerHTML = xhr.responseText; } }; xhr.open('GET", 'sidebar.html'); function sendAJAX() { xhr.send(); document.getElementById('load').style.display = "none"; };

</script>

It seems like there might be an issue with the script you provided. It looks like there's a syntax error in the xhr.open line. The string inside the open function should be enclosed in single or double quotes, but in your code, there's a mix of single and double quotes.

Here's the corrected version: 

xhr.open('GET', 'sidebar.html');

Make sure to replace the incorrect quotes with the correct ones. This should resolve the issue you're facing with the button not working. If the problem persists, please check for any error messages in the console or provide more details about the specific error you're encountering.
