Why am I not getting information from Marketplace Service? [closed]

I'm experimenting with Developer Products, but when I add the .ProcessReceipt, I'm not getting the correct information. PlayerID and ProductID both appear to be nil.

local mps=game:GetService("MarketplaceService")
function getPlayerWithID(id)
    print("Getting player...")
    print("Target player id is "..tostring(id))
    local plrs=game.Players:GetPlayers()
    for i=1,#plrs do
        print("Checking"..plrs[i].Name)
        if plrs[i].userId==id then print("Found player") return plrs[i] end
    end
end
function getValueWithID(id2)
    print("Getting product...")
    print("Target product id is "..tostring(id2))
    local items=game.Workspace.GameInfo.gI_CASH_DATA:GetChildren()
    for j=1,#items do
        if items[j].ProductID.Value==id2 then print("Found product") return items[j].CashValue.Value end
    end
end
mps.ProcessReceipt=(function(info)
    print("Something was purchased")
    print("player id is "..tostring(info.PlayerID))
    print("product id is "..tostring(info.ProductID))
    local plr=getPlayerWithID(info.PlayerID)
    local giveAmount=getValueWithID(info.ProductID)
    wait(1)
    if giveAmount~=nil then
        print("Dispensing cash")
        plr.leaderstats.Cash.Value=plr.leaderstats.Cash.Value+giveAmount
    else
        print("Purchase was not relevant to cash purchases")
    end
    return Enum.ProductPurchaseDecision.PurchaseGranted
end)

Thanks for helping out!

EDIT: I figured out what was wrong, ProductID and PlayerID are not the same as ProductId and PlayerId!
