when i buy a dev product i made for my game in studio. i dont get the coins?!

so basically when i bought the dev product i should have gotten the coins. but. i didn't. and i got a message in the output saying data store request.. i tried multiple different scripts... and its the exact same.. if you know how to fix this.. PLEASE tell me! (:

button GUI script:

local id = 1157603502
local mps = game:GetService("MarketplaceService")
local plr = game.Players.LocalPlayer


script.Parent.MouseButton1Click:Connect(function()
    mps:PromptProductPurchase(plr, id)
end)

Dev Product Handler Script:

local MarketPlace = game:GetService("MarketplaceService")
local id1 = 1157603502
id1Reward = 1000


MarketPlace.ProcessReceipt = function(receiptInfo)
    if receiptInfo.ProductId == id1 then
        local plr = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        plr.leaderstats.chords.Value = plr.leaderstats.chords.Value + id1Reward
        return Enum.ProductPurchaseDecision.PurchaseGranted

    end
end
