How do you get if the player owns a gamepass or not?

So when a player enters my game it detects it and checks if they own a pass. I do. However, whenever I go into the game, it says I don't own the pass.

Can anyone tell me why? Do I have to do something with the id; try a different method ect?

My script currently is:

local id = 00 

game.Players.PlayerAdded:connect(function(player)
	wait(1)
	local owns = game:GetService("GamePassService"):PlayerHasPass(player, id) 
	print(player,'owning the pass is', owns)

I've also tried using

game.GetService:("MarketPlaceService"):PlayerOwnsAsset(player, id)

but that also returns false

After this this I have the rest of the script saying

If owns == true then 
--rest of script

Or if I make it:

if owns then 

it just says 'GamepassIDHere' is not a gamepass, please use Marketplaceservice instead

But I still had nothing...

Can anyone help?

The way you require the MarketplaceService is wrong, it should be, like all GetService's, this:

game:GetService('MarketplaceService')

From there you can check for players owning assets, without this correctly formatted, it will not work.
