Need help using Skungee network variables

[sluhtie]

So I'm trying to make a playtime command using Skungee because I have a bungeecord network. So my Problem is that It gives me a error at my scheduler of ervery second.
Maybe someone could help me.

This is my Skript (proxy/plugins/Skungee/scripts):

Spoiler: Skript

options:
    prefix: &8┃ &eSky&6Squad &8&l◆

command /playtime [<offline player>]:
    aliases: pt
    trigger:
        arg-1 is not set:
            send "{@prefix} &7Deine Spielzeit &8● &e%network variable {playtime::days::%uuid of player%}%&ed %network variable {playtime::hours::%uuid of player%}%&eh %network variable {playtime::mins::%uuid of player%}%&em %network variable {playtime::seconds::%uuid of player%}%&es"
            stop
        else:
            if arg-1 has played before:
                network variable {playtime::seconds::%uuid of arg-1%} is set:
                    send "{@prefix} &7%arg-1%&7's Spielzeit &8● &e%network variable {playtime::days::%uuid of arg-1%}%&ed %network variable {playtime::hours::%uuid of arg-1%}%&eh %network variable {playtime::mins::%uuid of arg-1%}%&em %network variable {playtime::seconds::%uuid of arg-1%}%&es"
                    stop
                else:
                    send "{@prefix} &7Die Spielzeit dieses Spielers, ist nicht bekannt!"
                    playSound(player, "BLAZE_HIT")
                    stop
            else:
                send "{@prefix} &7Dieser Spieler war noch nie auf dem Server!"
                playSound(player, "BLAZE_HIT")
                stop
 
on join:
    if network variable {playtime::seconds::%uuid of player%} is not set:
        set network variable {playtime::seconds::%uuid of player%} to 0
    if network variable {playtime::mins::%uuid of player%} is not set:
        set network variable {playtime::mins::%uuid of player%} to 0
    if network variable {playtime::hours::%uuid of player%} is not set:
        set network variable {playtime::hours::%uuid of player%} to 0
    if network variable {playtime::days::%uuid of player%} is not set:
        set network variable {playtime::days::%uuid of player%} to 0
 
every second:
    loop all players:
        set network variable {playtime::seconds::%uuid of loop-player%} to network variable {playtime::seconds::%uuid of loop-player%}+1
        network variable {playtime::seconds::%uuid of loop-player%} = 60:
            set network variable {playtime::seconds::%uuid of loop-player%} to 0
            set network variable {playtime::mins::%uuid of loop-player%} to network variable {playtime::mins::%uuid of loop-player%}+1
            network variable {playtime::mins::%uuid of loop-player%} = 60:
                set network variable {playtime::mins::%uuid of loop-player%} to 0
                set network variable {playtime::hours::%uuid of loop-player%} to network variable {playtime::hours::%uuid of loop-player%}+1
                network variable {playtime::hours::%uuid of loop-player%} = 60:
                    set network variable {playtime::hours::%uuid of loop-player%} to 0
                    set network variable {playtime::days::%uuid of loop-player%} to network variable {playtime::days::%uuid of loop-player%}+1

This is my Error:
