Unfortunately, I didn't get an answer.

If you get an answer, let me know. I would like to know this too!

You have right. When I try it in that way, everything was right. I didn't now that the name of the function is also important. Thank you for your answer!

maybe the problem is that you have to put your solution in a funtion with the name "filter_list".

function filter_list(l) {
  // your solution here
}
