Why does this not work after I die?

This script is supposed to teleport you back and forth and it works until you die.

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

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

script.Parent.Lobby.MouseButton1Down:connect(function()
    for i = 1,25 do
        game:GetService("RunService").RenderStepped:wait()
        script.Parent.Lobby.TextColor3 = Color3.new(script.Parent.Lobby.TextColor3.r + .04,script.Parent.Lobby.TextColor3.g + .04,script.Parent.Lobby.TextColor3.b + .04)
        script.Parent.Lobby.BackgroundColor3 = Color3.new(script.Parent.Lobby.BackgroundColor3.r - .04,script.Parent.Lobby.BackgroundColor3.g - .04,script.Parent.Lobby.BackgroundColor3.b - .04)
        script.Parent.Lobby.BorderColor3 = Color3.new(script.Parent.Lobby.BorderColor3.r + .04,script.Parent.Lobby.BorderColor3.g + .04,script.Parent.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
    if script.Parent.Lobby.Playing.Value == false then
        chr.Torso.CFrame = CFrame.new(232, 3, 10)
        script.Parent.Lobby.Playing.Value = true
        script.Parent.TValue.Value = true
    else
        script.Parent.Lobby.Playing.Value = false
        script.Parent.TValue.Value = false
        chr.Torso.CFrame = CFrame.new(68, -142, -56)
    end
    for i =  0,1,.1 do
        game:GetService("RunService").RenderStepped:wait()
        frame.BackgroundTransparency = i
    end
    gui:Destroy()
end)

No errors either.
