Is there a solution to my gamepass money script?

I have a regular script located in my ServerScriptService and I have a auto-saving money script that goes with it so it can save my money. The auto-saver works fine but I just need to find out why my money currency is not adding when a player purchases or purchased a gamepass.

Gamepass Script:

local player = script.Parent.Parent
local leaderboard = player:WaitForChild("leaderstats")
local currency1 = leaderboard:WaitForChild("Money")

local id = 1289535025

game.Players.PlayerAdded:connect(function(player)
    if game:GetService("GamePassService"):PlayerHasPass(player, id) then 
        print(player.Name .. " has the game pass!")
        currency1.Value = currency1.Value + 500
    else
        print(player.Name .. " doesn't have the game pass...")
    end
end)

Just in case: Auto-Saver script:

local DataStore = game:GetService("DataStoreService"):GetDataStore("Money")

game.Players.PlayerAdded:connect(function(player)
    local key = "key-"..player.UserId
    local folder = Instance.new("Folder",player)
    folder.Name = "leaderstats"
    local currency1 = Instance.new("IntValue",folder)
    currency1.Name = "Money"

    local save = DataStore:GetAsync(key)
    if save then
        currency1.Value = save[1]
    else
        local load = {currency1.Value}
        DataStore:SetAsync(key,load)
    end
end)

game.Players.PlayerRemoving:connect(function(player)
    local key = "key-"..player.userId
    local load = {player.leaderstats:FindFirstChild("Money").Value}
    DataStore:SetAsync(key,load)
end)

Thanks!
