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!

I'm no mad evil genius but I think your having a script crash. This basically means you have a local that is breaking a function. Try this script instead.

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)

Also I wouldn't recommend using a gamepass for this, as players could just constantly rejoin and get cash. Look at Developer Products instead maybe.
