Why doesn't this work after I die?

This script is supposed to teleport you in and out of the lobby depending on if you're in the lobby or not. It works perfectly in studio but in game after I die i can't teleport out of the lobby but all the other button work. Works perfectly in studio though.

plr = game.Players.LocalPlayer
chr = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:wait()
lobby = script.Parent.Lobby
timer = script.Parent.Timer
lp = lobby.Playing
points = script.Parent.Points
--Lobby--
lobby.MouseEnter:connect(function()
	for i = 1,25 do
		game:GetService("RunService").RenderStepped:wait()
		lobby.TextColor3 = Color3.new(lobby.TextColor3.r - .04,lobby.TextColor3.g - .04,lobby.TextColor3.b - .04)
		lobby.BackgroundColor3 = Color3.new(lobby.BackgroundColor3.r + .04,lobby.BackgroundColor3.g + .04,lobby.BackgroundColor3.b + .04)
		lobby.BorderColor3 = Color3.new(lobby.BorderColor3.r - .04,lobby.BorderColor3.g - .04,lobby.BorderColor3.b - .04)
	end
end)

lobby.MouseLeave:connect(function()
	for i = 1,25 do
		game:GetService("RunService").RenderStepped:wait()
		lobby.TextColor3 = Color3.new(lobby.TextColor3.r + .04,lobby.TextColor3.g + .04,lobby.TextColor3.b + .04)
		lobby.BackgroundColor3 = Color3.new(lobby.BackgroundColor3.r - .04,lobby.BackgroundColor3.g - .04,lobby.BackgroundColor3.b - .04)
		lobby.BorderColor3 = Color3.new(lobby.BorderColor3.r + .04,lobby.BorderColor3.g + .04,lobby.BorderColor3.b + .04)
	end
end)

lobby.MouseButton1Down:connect(function()
	for i = 1,25 do
		game:GetService("RunService").RenderStepped:wait()
		lobby.TextColor3 = Color3.new(lobby.TextColor3.r + .04,lobby.TextColor3.g + .04,lobby.TextColor3.b + .04)
		lobby.BackgroundColor3 = Color3.new(lobby.BackgroundColor3.r - .04,lobby.BackgroundColor3.g - .04,lobby.BackgroundColor3.b - .04)
		lobby.BorderColor3 = Color3.new(lobby.BorderColor3.r + .04,lobby.BorderColor3.g + .04,lobby.BorderColor3.b + .04)
	end
	local gui = Instance.new("ScreenGui",plr.PlayerGui)
	local frame = Instance.new("Frame",gui)
	frame.Size = UDim2.new(1,100,1,100)
	frame.BackgroundTransparency = 1
	frame.BackgroundColor3 = Color3.new(0,0,0)
	for i =  1,0,-.1 do
		game:GetService("RunService").RenderStepped:wait()
		frame.BackgroundTransparency = i
	end
	print (lp.Value)
	print (chr.Torso.Position)
	if lp.Value == false then
		lp.Value = true
		chr.Torso.CFrame = CFrame.new(232, 3, 10)
	else
		lp.Value = false
		chr.Torso.CFrame = CFrame.new(68, -142, -56)
	end
	print (lp.Value)
	print (chr.Torso.Position)
	for i =  0,1,.1 do
		game:GetService("RunService").RenderStepped:wait()
		frame.BackgroundTransparency = i
	end
	gui:Destroy()
end)

--Points--
local stat = plr.Points

points.Text = stat.Value.." Points"

stat.Changed:connect(function(change)
    points.Text = tostring(change).." Points"
end)
--Timer--

chr:WaitForChild("Humanoid").Died:connect(function()
	timer:WaitForChild("Time").Value = 0
	timer.Text = "Dead"
end)

timer.Time.Changed:connect(function()
	if timer.Time.Value ~= 0 then
		timer.Text = "Time Alive: ".. timer.Time.Value.. " Seconds"
	end
end)

Another problem is my timer doesn't count. When you're playing it's supposed to start counting, and when you're in the lobby it's supposed to stop.

repeat wait() until script.Parent.Parent.Parent.Lobby.Playing

print 'found'

t = script.Parent.Parent.Parent.Lobby.Playing
chr = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:wait()
label = script.Parent.Parent
tim = script.Parent

while wait(1) do
	if t.Value == true then
		print 'true'
		if chr:WaitForChild('Humanoid').Health == 0 then
			tim.Value = 0
		else
			tim.Value = tim.Value + 1
		end
	end
end
