14,662 PointsHi Niels. The clue is in the question. They want 'platform' (shown in red) to become 'platform2', so don't change 'platforms.create'.

638 PointsI think what was confusing me is the word "command" and "string". would you be able to elaborate on this?

14,662 PointsYes I can. platforms.create is a "command" (also known as a function or in this case a method) which "does something". It creates the platforms in the game you saw in the previous video. The command is followed by parentheses () in which go the coordinates for the platform plus a plain text label (i.e. a name) for the platform, also known as a string which is enclosed in apostrophes (' ' or " ").
