command /bande [<text>] [<text>] [<text>]:
    trigger:
        if arg-1 is not set:
            send "     &4&lCool&8&lPrison &7&lBande     "
            send " "

        if arg-1 is "opret":
            if arg-2 is set:
                if player's balance is greater than 14999:
                    if {bande.%player%} is not set:
                        set {bande.%player%} to arg-2
                        set {bande.owner.%arg-2%} to offline player
                        set {bande.eco.%arg-2%} to 0
                        set {bande.member.%player%} to arg-2
                        add player to {bande.%arg-2%.members::*}
                        add arg-2 to {bande.list::*}
                        send "&aOpretter banden &7%arg-2%"
