problem z zmiennymi

# Sura

on region enter:
    if event-region is "test" parsed as region:
        set {SuraPart.%player%} to true
        
on region exit:
    if event-region is "test" parsed as region:
        set {SuraPart.%player%} to false

On rightclick:
    if player is holding Paper named "&bWyssanie Życia":
        if player has permission "sura.1":
            if difference between {Sura4::%player%::lastuse} and now is smaller than 35 seconds:
                send "&c35 Sekund Do Regeneracji Many Zaczekaj"
                stop
            set {Sura4::%player%::lastuse} to now
            if {SuraPart.%player%} is true   #<---(To Tutaj)
            loop all players within 10 meters of the player:
                damage loop-player by 3 heart
        else:
            send "<red>Nie Możesz Tego Używać."

dlaczego wyskakuje mi że nie istnieje entity type if {SuraPart.%player%} is true
