Not really a rule question, bu I am trying to score off the information at a college website. here is how the play is listed in the play by play:

Allison Podmajersky reached on a fielder's choice to shortstop, advanced to second, RBI; Kara Molnar advanced to second on an error by ss, advanced to third, scored on an error by rf.

The only way I could figure to score this in iScore is following:
In Play - Fielders Choice - for runner on first Second on Error SS - Batter held up. Then, with next batter up, tap runner on second - Home on Error LF.

Only problem I have with this is that the run shows that the batter was the next batter, not the one in the play.

What was the set up? Runners on what bases to start? And How many outs (important for RBI)

Did ss have a fielding error? AND left fielder a throwing error (say throw to third)?

Sounds like
in play fielders choice
What happen to runner on 1st? Home, error - left fielder (throw) (run unearned)

What happen to batter - second, error- SS (fielding)

The RBI suggests perhaps another runner on 3rd base with less than 2 outs. B/c i Would not credit an RBI for a runner who should have been out by FC except for SS error, or LF error.
