if own gamepass continue else ask to buy ?

So this script is supposed to check if the person owns the gamepass, and if he owns the gamepass it will do the following... if the person does not own the gamepass it should ask to purchase.

What is happening, it is just asking to purchase instead even tough I own the gamepass.

local player = game.Players.LocalPlayer	

function Click()

local id = 281057715	
if game:GetService("GamePassService"):PlayerHasPass(player, id) then
	
player.PlayerGui.ScreenGui.Extras.HorseColours.Visible = true
player.PlayerGui.ScreenGui.Extras.TycoonColours.Visible = false
player.PlayerGui.ScreenGui.Extras.Tracks.Visible = false

else
game:GetService("MarketplaceService"):PromptPurchase(player, id)	
end
end

script.Parent.MouseButton1Down:connect(Click)
