At the end of each round, verify that you have the answer sheet for every team, then open each of the following in order:
1. Round Points - Open tab for current round, sort by column C (table #).  If there are duplicates, delete the earlier entry and keep the later entry.  After the round has been sorted, CLOSE the Round Points, and open 2. Scores.  If you open 2. Scores before sorting the round points, it will permanently mess up the table order.
2. Scores - If you need to manually enter a score, do so on the "scoresheet" sheet.  Every other sheet in the workbook links to it for its data.
3. Scoreboard  

If you need to correct any of the answer sheets:
