Why does this teleport prior to the purchase?

In Central Alert I want you to have the user buy something that teleports you. It actually teleports you and never even mentions the purchase. Why doesn't this work? The first is the server script and the second is the client script.

local MarketplaceService = game:GetService("MarketplaceService")
local VIP = 19230420
local PurchaseHistory = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")

MarketplaceService.ProcessReceipt = function(receiptInfo) 
    -- find the player based on the PlayerId in receiptInfo
    for i, player in ipairs(game.Players:GetChildren()) do
        if player.userId == receiptInfo.PlayerId then
            -- check which product was purchased (required, otherwise you'll award the wrong items if you're using more than one developer product)
            if receiptInfo.ProductId == VIP then
                game.Workspace.Player.Torso.CFrame = CFrame.new(Vector3.new(10, 325.100006, 61, 1, 0, 0, 0, 1, 0, 0, 0, 1))
else
            end
        end 
    end
    -- record the transaction in a Data Store
    local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_purchase_" .. receiptInfo.PurchaseId
    PurchaseHistory:IncrementAsync(playerProductKey, 1) 
    -- tell ROBLOX that we have successfully handled the transaction (required)
    return Enum.ProductPurchaseDecision.PurchaseGranted     
end

local MarketplaceService = Game:GetService("MarketplaceService")
local buyButton = StarterGui.buyButton
local productId = 19230420

StarterGui.buyButton.MouseButton1Click:connect(function()
    MarketplaceService:PromptProductPurchase(player, productId)
end)

EDIT: The server script is StarterGui.buyButton.Script The client script is StarterPack.Script
