Previous Profit/Loss Bet settled in Hilo

Hi, all
I'm having a problem trying to finalize a trigger, I want to get previous profit/loss of a selection.

example
in game 1: I place 2 bet
Back card 1 or further   2 $ at 1.29
Back card 2 or further   3$ at 1.73
the game ended with Card 1 and Card 2 winner
so from Game 2:
I want a variable that get previous profit/loss of card 1 and another variable for the previous profit/loss of card 2.

Thanks in advanced.

Jim Patrick.
