Error: Invalid number of arguments passed to expression

[the dueces]

Sum(if[tourney_hand_player_statistics.flg_p_limp and (tourney_hand_player_statistics.amt_p_effective_stack / tourney_blinds.amt_bb) >= 8 AND (tourney_hand_player_statistics.amt_p_effective_stack / tourney_blinds.amt_bb) <= 12.99 AND lookup_actions_p.action = 'CF', 1, 0])

I get an error message on my HUD Error: Expression: Invalid number of arguments passed to function 'if' (Expecting 3, Received 2)
Is there a problem with above code?

I copied and pasted that and it validated for me. Are you sure you're in the right section (T, Players, Columns)?

[the dueces]

Yes i'm in - Tournaments - Players - columns

I'm new to creating custom stats is there something else I could have missed?

When I click the Validate button it says "expression is valid" it's just when my HUD loads up. I get the Error message I quoted in the first post, it's displayed in red writing on my HUD where the custom stat should be?
