I am not sure if this works?

I am unsure if I did this script right;

Note: Script edited from another user, credit to user

admin={"TheeDeathCaster"}

Game.Players.PlayerAdded:connect(function(Player)
if Player~=0 then
for i=1,#admin do
if string.lower(Player.Name)==string.lower(admin[i])then
Player.Chatted:connect(function(msg)
if string.sub(string.lower(1,5),msg) == "kill/" then
findplayer=game:FindService("Players"):FindFirstChild(string.lower(msg,5))
findplayer.Character:BreakJoints()
end end)end end end end)
