I think @muneer’s suggestion was to use labels to display intermediate steps in your code. So instead of running the entire set of blocks and wondering why it doesn’t work, you can debug your code by adding “set label’s text to” blocks every so often and checking values that you are getting from blocks (e.g. from JSON, etc.). You can even put Wait blocks and/or Vibrate blocks in so that you know where you are in the code when something does/does not work.
