My buy script isn't working. It only gives u the tool and doesn't take money from u. Please Help!?

Scripts:

local data = game:GetService("DataStoreService"):GetDataStore("Hack3214234hg")
game.Players.PlayerAdded:connect(function(plr)
    local stats = Instance.new("Folder",plr)
    stats.Name = "leaderstats"

    local Money = Instance.new("NumberValue",stats)
    Money.Name = "Money"

    local SavedItems = data:GetAsync(plr.UserId)
    if SavedItems then
        Money.Value = SavedItems.Money or 20
    else
        Money.Value = 20
    end
end)

script.Parent.MouseButton1Click:connect(function()
    local price = script.Parent.Parent.Price
    local player = game.Players.LocalPlayer
    if game.Players.LocalPlayer.leaderstats.Money.Value >= price.Value then
        local item = script.Parent.Parent.Item
        local backpack = player.Backpack
        local starter = player.StarterGear
        local clone = game.ReplicatedStorage.Tools:FindFirstChild(item.Value):Clone()
        local clone2 = game.ReplicatedStorage.Tools:FindFirstChild(item.Value):Clone()
        clone.Parent = backpack
        clone2.Parent = starter
        game.ReplicatedStorage.Buy:FireServer()
    end
end)

game.Players.PlayerRemoving:connect(function(plr)
    local Saving = {["Money"] = plr.leaderstats.Money.Value;
    }
    data:SetAsync(plr.UserId,Saving)
end)

game.ReplicatedStorage.Buy.OnServerEvent:Connect(function(player)
    player.leaderstats.Money.Value = player.leaderstats.Money.Value - player.Price.Value
end)

It doesnt save the leaderstats if i have it in a local script...
