For the method .toUpperCase() to work, you'll need to add the parenthesis to the end of it.

Ah, it says to pay close attention to the spacing. There needs to be a space after the colon.

Also, the period at the end isn't part of the request, so remove it. I just attempted the the challenge with the period on there and it wouldn't accept the answer as correct.

So the question before this one I struggled with as well because I didn't add the period in the end and then when I did it work, but in this one iv'e tried both with and without and can't get it to work. In the question before everything was fine and i was only suppose to add so that developer was upper case in this one.
