Why wont this button work?

Im trying to make a button that hides a whole gui for my clicker game so i can make a sword fighting room.

script.Parent.MouseButton1Click:connect(function ()
if script.Parent.Text == "Hide Game" then
game.StarterGui.Game.Background = false
script.Parent.Text = "Show Game"
else
game.StarterGui.Game.Background = false
script.Parent.Text = "Hide Game"
end
end)`

I've already tried:

script.Parent.MouseButton1Click:connect(function ()
if script.Parent.Text == "Hide Game" then
game.Players.LocalPlayer.PlayerGui.Game.Background = false
script.Parent.Text = "Show Game"
else
game.Players.LocalPlayer.PlayerGui.Game.Background = false
script.Parent.Text = "Hide Game"
end
end)`

But you also have to add the ending right? Like this.

script.Parent.MouseButton1Click:connect(function ()
    if script.Parent.Text == "Hide Game" then
        game.Players.LocalPlayer.PlayerGui.Game.Background.Visible = false
        script.Parent.Text = "Show Game"
    else
        game.Players.LocalPlayer.PlayerGui.Game.Background.Visible = true
        script.Parent.Text = "Hide Game"
    end
end)

script.Parent.MouseButton1Click:connect(onClicked)
