Problem z argumentem

Witam! Piszę, ponieważ posiadam problem, że gdy tworze - nawet najprostszy - skrypt z argumentem to wywala błąd, lecz gdy zrobiłem ten sam skrypt, jednakże bez argumentów to działał bez problemu. Screeny pluginów, skrypt, screen błędu w consoli poniżej, z góry dziękuję .

Skrypt:

command /chat [<text>]:
    trigger:
        if arg 1 is "cc" or "clear":
            if player has permission "chat.cc":
                loop 128 times:
                    broadcast ""
                broadcast " &8> &9Chat zostal wyczyszczony przez: &6%player%"
                stop

Pluginy+reload:

Błąd w Konsoli:
