Hi, I'm trying to get the top 5 values of objects but doesnt works
Skript version: 2.2 fixesv8 (Im running 1.8.8) and using MirrorUtils.sk
Addons: skript-mirror 2.0.0

Here's my code

command /top [<text>]:
    usage: /top <kills|deaths>
    trigger:
        if arg-1 is set:
            if arg-1 is "kills":
                set {_top::*} to top 5 elements of {kills::*} as "&f##<pos>. &e<index> &7- <value>"
                loop {_top::*}:
                    send "%loop-value%"
                stop
            else if arg-1 is "deaths":
                set {_top::*} to top 5 elements of {deaths::*} as "&f##<pos>. &e<index> &7- <value>"
                loop {_top::*}:
                    send "%loop-value%"
                stop
        else:
            send "&cUsage: /top <kills|deaths>"
