Kohls admin script doesn't work. Is it broken due to roblox updates?

Everytime i try to use a command like :fly me it wont work and here is the script:

Use usernames or userIds to add a user to a list
For example;    Admins={'MyBestFriend','Telamon',261}       ]]

local Banned={'someoneyoudislike'} -- For those who have wronged you, & this guy

--------------------------------------------------------------
-- You DO NOT need to add yourself to any of these lists!!! --

local Owners={}                 -- Can set SuperAdmins, & use all the commands
local SuperAdmins={}            -- Can set permanent admins, & shutdown the game
local Admins={}                 -- Can ban, crash, & set Moderators/VIP
local Mods={}                   -- Can kick, mute, & use most commands
local VIP={}                    -- Can use nonabusive commands only on self
