I can see two issues:

  • you wrote "backGroundColor" (with capital "G") instead of "backgroundColor" (little "g")
  • "backgroundColor" is not a method you can call, but it is a property you can assign

That 2nd one is causing a syntax error, and those invalidate the entire script. That's why the re-test of task 1 is failing.

Thank you very much, Steven.
