Zmienna nie dziala

Witam! Postanowilem zrobic topke na komende na czacie i mam pytanie dlaczego zmienna nie zmienia swojej wartości?

on death of player:
    attacker is player
    if {zabojstwa::%attacker%} is not set:
        set {zabojstwa::%attacker%} to 1
        stop
    add 1 to {zabojstwa::%attacker%}

command /top:
        trigger:
                set {_s} to size of {zabojstwa::*}
                loop {_s} times:
                        loop {zabojstwa::*}:
                                if {_v.%loop-number%} is not set:
                                        set {_v.%loop-number%} to loop-value
                                        set {_n.%loop-number%} to loop-index
                                if loop-value is larger than {_v.%loop-number%}:
                                        set {_v.%loop-number%} to loop-value
                                        set {_n.%loop-number%} to loop-index
                        remove {_v.%loop-number%} from {zabojstwa::*}
                loop {_s} times:
                        if loop-number is smaller than or equal to 5:
                                send "&6%loop-number%. &cGracz %{_n.%loop-number%}% &aZabojstw: %{_v.%loop-number%}%"
                        set {zabojstwa::%{_n.%loop-number%}%} to {_v.%loop-number%}

command /staty:
        trigger:
                send "%{zabojstwa::%player%}%"

takie cos mi tylko wyskakuje
