How to update leaderboard lives after developer purchase?

I have a developer purchase which activates and says successful but will not give the lives to the character for the purchase here is the two scripts im using for the leaderboard and the purchase.

Here is the Leaderboard Script

game.Players.PlayerAdded:Connect(function(plr)
    local Stats = Instance.new('Folder') 
    Stats.Name = 'leaderstats'
    Stats.Parent = plr

    local Lives = Instance.new('IntValue')
    Lives.Name = 'Souls'
    Lives.Value = 25
    Lives.Parent = Stats

    local Stage = Instance.new('IntValue')
    Stage.Name = 'Stage'
    Stage.Value = 0
    Stage.Parent = Stats

    local Timer = Instance.new('IntValue')
    Timer.Name = 'Time'
    Timer.Value = 0
    Timer.Parent = Stats

    plr.CharacterAdded:Connect(function(char)
        char.Humanoid.Died:Connect(function()
            Lives.Value = Lives.Value -1
            if Lives.Value <= 0 then
                char:SetPrimaryPartCFrame(workspace.Starter.CFrame)
                Stage.Value = 0
                Lives.Value = 25


            end
        end)
    end)

    while true do
        wait(1)
        Timer.Value = Timer.Value +1
    end
end)

Here is the Purchase Script

local Lives = game.Workspace.Leaderboard
local mpService = game.getService("MarketplaceService")

mpService.ProcessReceipt = function(purchaseInfo)
    local plr = game:GetService("Players"):GetPlayerByUserId(purchaseInfo.PlayerId)
    if purchaseInfo.ProductId == 55131820 then
        Lives.Value = Lives.Value +1
    end
    return Enum.ProductPurchaseDecision.PurchaseGranted
end

If anyone can help me figure out what is wrong it would be great. I've been stuck on this for awhile now and can't get past it. Thank you
