I have recently scored a softball game, and in that game there were 4 errors on the home team.
While in the app I see the 4 errors listed in the box score.
In my . iscorecentral the box score for the game shows 0 errors.

Why the difference?

That will happen if you assigned errors to the Home Team on positions that did not have a player assigned. The box score at my.iscorecentral.com only shows errors that were actually assigned to people. If you have a "?" on a fielding position, it means a player has not been assigned to that position. You can still assign an error, but the assumption is you will go back and plug in the missing position post game, and the error will be assigned to the correct player.

If you go to the Play by Play listing for the game, select the Game Starts event, select Edit next to Starting Lineup, and make sure there is a player assigned to each position for the home team, then do the Options -> Export again, then box score should then add up correctly on my.iscorecentral.com as well.

Makes sense.
Thanks for the explanation.
