What do I do if the scorers disagree or a coach thinks there's an error?

Under the NFHS scorers and timers instructions:

• The official scorer checks constantly with the visiting team's scorer.
• If there's any disagreement about the score, the official scorer immediately tells the match timekeeper and makes sure the scoreboard operator and assistant scorers show the correct score.
• The match timekeeper notifies the referee of any disagreement between the scorer and timekeeper, or when a coach asks to discuss a possible error.
• When asked, the timekeeper helps the referee decide whether something happened before or after the end of a period.

At the end of a dual meet, the official scorer gives the scorebook to the referee, who verifies the team scores and signs it.
