Remember that completing a challenge is about accomplishing a particular goal, not just creating code that "works" without errors.

:point_right: It looks like you have two issues here:

  • you seem to have too many spaces in the join string (it should have one comma and one space).
  • the challenge wants to you assign the result of the formatted string back to menu.
