Code not working due to 'ul' changing to a global scope.

I spent an hour trying to find the issue. I finally DL'ed the final code for this project and ran it in workspace and got the same error message. So it wasn't my fault, this time. LoL!!

app.js:25 Uncaught TypeError: Cannot read property 'appendChild' of null at HTMLFormElement.form.addEventListener (app.js:25)

Please use the "snapshot" function in the workspace, and post the link it gives you here so we can see your code.
