Trying to script skip stage, it teleports me but not to the stage, what am I doing wrong?

I've tried multiple things but still can't get it to work, here's the code

local MarketplaceService = game:GetService('MarketplaceService')

local function processReceipt(receiptInfo)
    local player = game:GetService('Players'):GetPlayerByUserId(receiptInfo.PlayerId)
    if not player then
        --Player doesn't exist / left game.
        return Enum.ProductPurchaseDecision.NotProcessedYet
    end
    --Script below controls what happens if bought.
    print(player.Name .. ' just bought ' .. receiptInfo.ProductId)
    player.leaderstats.Stage.Value = player.leaderstats.Stage.Value + 1
    player.Character:MoveTo(Vector3.new(player.leaderstats.Stage.Value))
    return Enum.ProductPurchaseDecision.PurchaseGranted
end

MarketplaceService.ProcessReceipt = processReceipt

Thanks, for your service.
