How do i make a player leave a game when they die?

iv tried multiple things but none works, this is what I have so far but I cannot find where the player's health is so it wont trigger if they reset, Please help. Here is the script

function waitForChild(parent, childName) local child = parent:findFirstChild(childName) if child then return child end while true do child = parent.ChildAdded:wait() if child.Name==childName then return child end end end

function onDied() endgame:GetService("TeleportService"):Teleport(1520637787,game.Players.LocalPlayer) end

Humanoid.Died:connect(onDied)

Please help if you know how
