How do i add cash to a player from a gamepass?

Im trying to make a game pass that gives a bunch of cash when bought however I don't know how to properly access the leader stats to add more cash. ** This is my Code for the server script part of the game pass**

local RS = game:GetService("ReplicatedStorage")
local sword = RS:WaitForChild("Sword")
local currencyName = "Cash"
local gamePass = game:GetService("MarketplaceService")
gamePassId = 15489874

gamePass.PromptGamePassPurchaseFinished:Connect(function(player, passId, purchaseSuccess)
	if purchaseSuccess and passId == gamePassId then 
		local player = game.Players:GetPlayers()
local stats = player:FindFirstChild("leaderstats")
stats[currencyName].Value = stats[currencyName].Cash.Value + 34567
		print(" purchases was successful")
	end
	
end)

**This is my code for the local script **

local gamePass = game:GetService("MarketplaceService")
gamePassId = 15489874
local function Pass ()
local player = game.Players.LocalPlayer
	local check = false 
	local success, error = pcall(function()
		check = gamePass:UserOwnsGamePassAsync(player.UserId, gamePassId)
	end)
	if check then
		gamePass:PromptGamePassPurchase(player, gamePassId)
		print("Pass owned")
	else 
		gamePass:PromptGamePassPurchase(player, gamePassId)
		print("Getting pass")
	end

end
wait(5)
Pass()

This is the code that I would use hope it helps just make another script that is the leader board and change the value of cash other than that you can just copy and paste this. if this helps please mark it as answered.

local Cash = game.Players.LocalPlayer.leaderstats.Cash -- Don't add .Value at the end of this
local Amount = 100

local passId = 15489874
local marketplaceService = game:GetService("MarketplaceService")

marketplaceService.PromptPurchaseFinished:connect(function(player,assetId,isPurchased)
    if isPurchased then
        if assetId == passId then
            Cash.Value = Cash.Value + Amount
        end
    end
end)
