Kill command not working ( custom admin )?

kill = (function(sender, arguments,message, recipient) 
	if sender.AdminRankID.Value >= 1 then
		if arguments[2] then
			local target = findplayer(arguments[1])
			local char = target.Character
			char.Humanoid.Health = 0
		end
	end
end);

It seems like your checking for arguments[2], when arguments[1] is the player. So. If you do /kill [user]. [User] seems to be arguments[1] and arguments[2] will be nil, stopping the script. Try changing if arguments[2] to if arguments[1]
