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!!! --
