Player's purchase doesn't subtract the player's money in the leaderstat, why?

for j, l in pairs(button:GetChildren()) do
        if l.BuyButton.Transparency ~= 1 then
            l.BuyButton.Touched:Connect(function(hit)
            local player = game.Players:GetPlayerFromCharacter(hit.Parent)
            local money = player.leaderstats.Money.Value
            local cost = l.Cost.Value
                    if money >= cost then
                money = money - cost
                print(money) -- when I print it out, the player's money got subtracted but not in the leaderstats
                        for i, v in pairs(FurnitureTable) do
                            if v.Name == l.Purchase.Value then
                                v.Parent = items
                            end
                        end
                    end
                end)
        end
    end

hello, i made a purchase script where when a player touched a button it will subtract the player's money and the item will be purchased. But, the player's money doesn't get subtracted for a reason.
