Selections p/l after event is settled

Hey,

So I'm trying to use the selections settled p/l in calculations but can't seem to get it working. I have different bets on the 1st 4 faves so I can't use the market settled p/l for these calculations. It has to be specific to the runner so I'm trying to calculate a running total pl for each selection so it should start at 0 and then plus whatever the settled pl is for that runner. I've tried using selections profit/loss conditions and selections trigger expression profit/loss but these don't work so I'm assuming you can't use these for settled markets. Any idea how I can calculate the settled p/l for each selection? Cheers.
