Why Won't this work?

It's meant to show a Video Ad and give the player his reward, but nothing happens... Help? No output too...

debounce = false
script.Parent.Touched:connect(function()
	if debounce == false then
		debounce = true
		game:GetService("AdService"):ShowVideoAd()
	end
end)
game:GetService("AdService").VideoAdClosed:connect(function()
	local a = math.random(1,10)
	game.Players.LocalPlayer.stats.Cash = game.Players.LocalPlayer.stats.Cash + a
	game.Players.LocalPlayer.PlayerGui.ScreenGui.Notice.TextButton.Text = "You have earnt "..a.." Cash from the Video."
	wait(60)
	debounce = false
end)

I'm fairly certain that it's LocalPlayer.stats. Those stats aren't meant to be visible to anyone but the player.
