Error when player stands on part?

This script doesn't work you can test it out for yourself it shows an error when you stand on the part that the script has, so I would likely wanna see if anyone can do a better script. The Error Is "Your purchase failed because something went wrong. Your account has not been charged. Please try again later.

Code:`local Marketplace = game:GetService('MarketplaceService') local gamepassid = 1208800558

script.Parent.Touched:connect(function(t) if t and t.Parent and t.Parent:FindFirstChild('Humanoid') then local Player = game.Players:FindFirstChild(t.Parent.Name) if Player then Marketplace:PromptGamePassPurchase(Player, gamepassid) end end end)`
