How do i make a gamepass that removes a wall?

It is all in the question really. I've tried multiple ways as such as using a gui rather than touching the part, the gui worked better as it actually prompted the purchas unlike the part being touched. To prompt the purchase i have put a local script into a frame, which includes this code :

script.Parent.TextButton.MouseButton1Click:Connect(function()
	script.Parent.Visible = false
end)

local UserInputService = game:GetService("UserInputService")
local frame = script.Parent
local topBar = frame:WaitForChild("TopBar")
local Camera = workspace:WaitForChild("Camera")
local DragMousePosition
local FramePosition
local Draggable = false

topBar.InputBegan:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
		Draggable = true
		DragMousePosition = Vector2.new(input.Position.X, input.Position.Y)
		FramePosition = Vector2.new(frame.Position.X.Scale. frame.Position.Y.Scale)
	end
end)

topBar.InputEnded:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
		Draggable = false
	end
end)

UserInputService.InputChanged:Connect(function(input)
	if Draggable == true then
		local NewPosition = FramePosition + ((Vector2.new(input.Position.X, input.Position.Y) - DragMousePosition) / Camera.ViewportSize)
		frame.Position = UDim2.new(NewPosition.X, 0, NewPosition.Y, 0)
	end
end)

To make the gamepass actually do something when bought I've put a script into serverscript service which the code for it is :

local MPS = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
local conveyorID = 18801304

game.Players.PlayerAdded:Connect(function(player)
	local success, message = pcall(function()
		hasPass = MPS:UserOwnsGamePassAsync(player.UserId, conveyorID)
	end)
	
	if hasPass then
		print("player has the gamepass")
		
		local conveyorBorder = game.Workspace.MainBuild.MainConveyor.ConveyorBorder
		conveyorBorder.Transparency = 1
		conveyorBorder.CanCollide = false
	end
end)

local function onPromptGamePassPurchaseFinsihed(player, purchasedPassID, purchaseSuccess)
	if purchaseSuccess == true and purchasedPassID == conveyorID then
		print(player.Name .. " purchased the conveyor gamepass")
		local conveyorBorder = game.Workspace.MainBuild.MainConveyor.ConveyorBorder
		conveyorBorder.Transparency = 1
		conveyorBorder.CanCollide = false
	end
end

MPS.PromptGamePassPurchaseFinished:Connect(onPromptGamePassPurchaseFinsihed)		

The problem is, is that when i tested it out with a game even tho my friend had not bought the wall completely dissapeared. I'm in desprete need of help because if i dont figure out this i can't continue making my game :/. I think it's somewhere in the code but i can't see it, probably because im new to scripting. I'm reasking the question with more context and like i said i went from using a part touch for activating the prompt purchase to a gui.

First, put a local script in starterGui and here’s the script:

local MarketplaceService = game:GetService(“MarketplaceService”)
local Player = game.Players.LocalPlayer

local doorPart = game.Workspace.Door.Door
local gamepassId = yourGamepassID

if MarketplaceService:UserOwnsGamePassAsync(Player.UserId, gamepassId) then
      print(“Player Owns Pass.”)
      doorPart.CanCollide = false
      doorPart.Transparency = 1
else
       print(“Player Does Not Own Pass.”)
       doorPart.CanCollide = true
       doorPart.Transparency = 0
end

and make sure to replace ‘yourGamepassID’ with the gamepass Id.

Then, make a model inside workspace named Door and inside of Door, add 4 parts in it and name the first Door, the second DoorFrame, and the third and forth name those DoorFrame.
