Hi Prerna

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
