Hi there, Marcell Ciszek ! You might feel confused, but it looks to me like you're doing brilliantly! You passed the function as an anonymous function just fine into the functionRunner, but you forgot to remove the code that isn't necessary anymore. Deleting the top line of your code causes this to pass the challenge.

Hope this helps and well done! :sparkles:
