What is wrong with this script?

It does not work via an error.

local Saying = game.Players.Chatted:connect()

if Saying.msg:sub(1,5) "kill " then
	vic = msg:sub(1,9)
	vic:WaitforChild("Character")
elseif vic:BreakJoints() then
vic.Character.Health = 0
end -- No problem here just in Developer Thing it says That Chatted is not a valid member of Players

game.Players.PlayerAdded:connect(function(player)
player.Chatted:connect(function(msg)
--stuff
--stuff
end)
end)
