How to make a open/close Text button GUI into a gamepass ?

You have already asked this question before, and I have already answered it. You can find the question right here -- However, here is a more updated code, because now I know where your buttons are located so that I can make the entire script. For guidance, go to my previous answer. Here is the same code as last time, but completed because I know where the frame is:

-- local script inside the button
local allow = false
local Player = game.Players.LocalPlayer
if game.MarketplaceService:PlayerOwnsAsset(Player,773709832) then -- checks if he has it, again, replace the id
    allow = true -- sets a variable to true
end
--( they will have to reset after purchasing the gamepass)
script.Parent.MouseButton1Down:Connect(function()
    if allow then-- if they have it, do which ever you want
script.Parent.Parent.Frame.Visible = true -- here is your new line.
    else -- if they do not have it, ask them to purchase
        game.MarketplaceService:PromptPurchase(Player, 773709832) -- change the number to the ID of the gamepass, found in its link of your gamepass
    end
end)
