How would I make a gamepass to award the player with points?

I have made a script that somebody helped me out with on this website, I edited it so it would give the person "Lifts" (basically money) and in studio it works but when I test the actual game it doesn't, help please?

local Player = game.Players.LocalPlayer
local passOwners = {} --add to this table if they buy it in game, so they don't have to rejoin
game.Players.PlayerAdded:Connect(function(plr)
    passOwners[plr.Name] = game:GetService("MarketplaceService"):UserOwnsGamePassAsync(plr.UserId, 4643667)
    plr.CharacterAdded:Connect(function(char)
        if passOwners[plr.Name] then
            Player:WaitForChild("leaderstats").Value = 1000000
Player:WaitForChild("Lifts").Value = 1000000
        end
    end)
end)
