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.
