How to disable script outside of Lobby? (repost)

Hello!

I am re-posting this question, as there was no suggestions for my last question. I've tried additional methods in the days since, but have not had any success. Any help would be very much appreciated. :)

I have a Spectate mode script that works, everywhere, but I'd like it to only work while inside the Lobby.

Currently, I have the "ResetOnSpawn" box checked so that when a player dies in the game, the Spectate Mode is reset when they reappear in the Lobby, but if the player has it turned on while in the Lobby, when they teleport to the Game Map, Spectate Mode is still on.

Is there an easy way to do it? I know the code below is horribly wrong, but its where I've started. Any suggestions is appreciated. Thank you! :)

local players = nil
local number = 1
local maxnumber = 0
local player = game.Players.LocalPlayer

-- Broken Script Below
if player.Lobby then player.PlayerGui.SpectateGui = true
else player.PlayerGui.SpectateGui = false
end
-- Broken Script Above



script.Parent.Next.MouseButton1Click:connect(function(right)
    players = game.Players:GetChildren()
    number = number + 1
    if players[number] ~= nil then
        game.Workspace.CurrentCamera.CameraSubject = players[number].Character.Humanoid
        if players[number].Name ~= player.Name then
            script.Parent.PlayerName.Text = players[number].Name
        else 
            script.Parent.PlayerName.Text = "Nobody"
        end
    elseif players[number] == nil then
        number = 1
        game.Workspace.CurrentCamera.CameraSubject = players[number].Character.Humanoid
        if players[number].Name ~= player.Name then
            script.Parent.PlayerName.Text = players[number].Name
        else 
            script.Parent.PlayerName.Text = "Nobody"
        end
    end
end)

script.Parent.Previous.MouseButton1Click:connect(function(left)
    players = game.Players:GetChildren()
    maxnumber = #players
    number = number - 1
    if players[number] ~= nil then
        game.Workspace.CurrentCamera.CameraSubject = players[number].Character.Humanoid
        if players[number].Name ~= player.Name then
            script.Parent.PlayerName.Text = players[number].Name
        else 
            script.Parent.PlayerName.Text = "Nobody"
        end
    elseif players[number] == nil then
        number = maxnumber
        game.Workspace.CurrentCamera.CameraSubject = players[number].Character.Humanoid
        if players[number].Name ~= player.Name then
            script.Parent.PlayerName.Text = players[number].Name
        else 
            script.Parent.PlayerName.Text = "Nobody"
        end
    end
end)

script.Parent.Parent.SpectateButton.Spectate.MouseButton1Down:connect(function(click)
    if script.Parent.Parent.Active.Value == false then
        script.Parent.Parent.Active.Value = true
        script.Parent.Parent.ChangePlayer.Visible = true
    elseif script.Parent.Parent.Active.Value == true then
        script.Parent.Parent.Active.Value = false
        script.Parent.Parent.ChangePlayer.Visible = false
        script.Parent.PlayerName.Text = "Nobody"
        number = 1
        game.Workspace.CurrentCamera.CameraSubject = game.Players.LocalPlayer.Character.Humanoid
    end
end)
