Calculating all possible situations for 3 handed play is not going to be straightforward - see this thread.

I created a player column stat val_p_total_3bet sum(if[cash_hand_player_statistics.flg_p_3bet, cash_hand_player_statistics.amt_p_raise_made_2 / cash_limit.amt_bb, 0]) and a custom player stat Avg 3Bet Size if( cnt_p_3bet > 0, (val_p_total_3bet / cnt_p_3bet), 0 ) It gives an output but not the one I...

No because 'Fold to PF 3Bet After Raise' also includes 2bets vs limpers and it's not possible to steal when there are limpers.

That is not validating because there is a bracket mismatch so if you tidy those up the expression will validate. Check all the open and close brackets in your expressi...

when I just replace (lookup_actions_ t .action SIMILAR TO '(F|XF)%') with (lookup_actions_ r .action SIMILAR TO '( F|XF)%') the statistic is "not valid" If you remove the line breaks it will validate: cnt_r_bet_def_action_fold_10more sum(if[lookup_actions_f.action = 'X' AND lookup_actions...

So we can investigate this please turn on 'Enable Logging' in PokerTracker 4 via 'Configure -> Options' and then restart PokerTracker 4.
