Uncaught TypeError:Cannot set property 'innerHTML' of null at XMLHttpRequest.xhr.onreadystatechage.

You need to post your code in between two sets of three backticks so we can help you. See the markdown cheatsheet below. I have noticed that you missed out the 'n' in onreadystatechage => onreadystatechange. But I don't think thats your problem.
Null means basically that something doesn't exist, or that it at least cannot find a reference to it. Check the spelling of all your variables/functions first.
Hope this helps Happy coding
