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
