Double error?

[triple]

R1 at 1B, R2 at 2B
Batter hits the ball to the outfield for a single base hit.
The fielder misjudged the ball resulting with the 2 runners taking an extra base (R2 scores)

Following this error, how to score this 1 error instead of 2, because for each runners, iScore ask what happened...

R2 scored on the error but what about R1 who also took advantage of the same error and, as a scorekeeper, I cannot credit the outfielder with 2 errors, so,

. how should I score the extra base taken by R1?
. Is the batter gets a RBI on this play?

If you enter 2 errors assigned to the same fielder during a play, it only charges one error to the fielder.

A base hit to the outfield will often score a runner on 2nd, but it would be scorekeeper judgment whether the run would have scored without the error. If in your judgment the run would have scored without the error, then the runner should be entered as Safe, Home, Advanced by Batter (and the batter will get an RBI). If the runner would not have scored without the error, then you would enter Safe, Home, Error, (select Fielder) and Batter will not be given an RBI.

If you assign multiple errors to same player on same play, iscore will only charge one error. advance both players by error on OF. No rbi if the runner truly scored on this error.
