SkQuery Permissions

[Mr_pro68YT]

I heard there was a permission manager in skQuery but it isn't working. I get these errors.

Code:

script options:
    $ use permissions
options:
    noperm: &f&l<&c&l!&f&l> &7No Permission! &f&l<&c&l!&f&l>

command perm [<player>] [<text>] [<text>]:
    permission: skript.admin
    permission message: "{@noperm}"
    trigger:
        if arg-1 isn't set:
            if arg-2 is set:
                if arg-2 is "add" or "give":
                    if arg-3 is set:
                        add arg-3 to permissions of player
                else if arg-2 is "take" or "remove":
                    if arg-3 is set:
                        remove arg-3 from permissions of player
        if arg-1 is set:
            if arg-2 is set:
                if arg-2 is "add" or "give":
                    if arg-3 is set:
                        add arg-3 to permission of arg-1
                else if arg-2 is "take" or "remove":
                    if arg-3 is set:
                        remove arg-3 from permission of arg-1
