WARNING: This program has a bug, which means that we need to debug it!

RULE: Any command that will be repeated in the loop needs to be indented underneath the first line of the loop.

An indent is 4 spaces, or 1 tab.

  • Click Run and read the error message.
  • Debug the program so that the butterfly zigzags across the stage.

To navigate the page using the TAB key, first press ESC to exit the code editor.
