I made a gamepass script in Roblox but it's not working?

So basically this is my script `` -- This code should be within a 'LocalScript' object local MarketplaceService = game:GetService("MarketplaceService") local Players = game:GetService("Players")

local gamePassID = 6738501 -- Change this to your game pass ID

-- Function to prompt purchase of the game pass local function promptPurchase()

local player = Players.LocalPlayer
local hasPass = false

local success, message = pcall(function()
    hasPass = MarketplaceService:UserOwnsGamePassAsync(player.UserId, gamePassID)
end)

if not success then
    warn("Error while checking if player has pass: " .. tostring(message))
    return
end

if hasPass == true then
    -- Player already owns the game pass; tell them somehow
else
    -- Player does NOT own the game pass; prompt them to purchase
    MarketplaceService:PromptGamePassPurchase(player, gamePassID)
end

-- This code should be within a 'LocalScript' object
local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")

local gamePassID = 6738501  -- Change this to your game pass ID

-- Function to prompt purchase of the game pass
local function promptPurchase()

    local player = Players.LocalPlayer
    local hasPass = false

    local success, message = pcall(function()
        hasPass = MarketplaceService:UserOwnsGamePassAsync(player.UserId, gamePassID)
    end)

    if not success then
        warn("Error while checking if player has pass: " .. tostring(message))
        return
    end

    if hasPass == true then
        -- Player already owns the game pass; tell them somehow
    else
        -- Player does NOT own the game pass; prompt them to purchase
        MarketplaceService:PromptGamePassPurchase(player, gamePassID)
    end

So can u help me
