why wont this script prompt the user to buy a gamepass?

to incapez: I TRIED MYSELF BUT IT DIDNT WORK, STOP BEING SUCH A PICKY MOD

when a brick in workspace called 'gss' is touched, it is supposed to prompt the touched to buy a gamepass or make a gui that says s/he already owns it.

this is a LOCAL SCRIPT in STARTERPACK

-- Localscript
repeat wait() until game.Players.LocalPlayer and game.Players.LocalPlayer.Character
local player = game.Players.LocalPlayer
local character = player.Character
local block  = game:GetService'Workspace':WaitForChild("gss")

local debounce = false

block.Touched:connect(function(p)

    if debounce then return end
    debounce = true
-- This code can be within a 'LocalScript' object
local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")

local gamePassID = 3682933  -- 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.PlayerGui.owned.Text.Visible = true
    wait(3)
        player.PlayerGui.owned.Text.Visible = false

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


local function onPromptGamePassPurchaseFinished(player, purchasedPassID, purchaseSuccess)

    if purchaseSuccess == true and purchasedPassID == gamePassID then
        print(player.Name .. " purchased the game pass with ID " .. gamePassID)
player.Character.Humanoid.Health.Value = 0
player:LoadCharacter()
        -- Assign this player the ability or bonus related to the game pass
        --
    end
end

    MarketplaceService.PromptGamePassPurchaseFinished:Connect(onPromptGamePassPurchaseFinished)



end
debounce = false
end)
