I did this Speed Upgrade Thing But I want It to take Money away How do I do it?

When you are trying to remove the money and check it, you are forgetting to add .Value. This is required to get the value of a Value Object.

button = script.Parent
player = game.Players.LocalPlayer
char = player.Character
humanoid = char.Humanoid
price = 50
speed = 17
max = false

button.MouseButton1Click:connect(function()
if humanoid.WalkSpeed == 140 then   


if player.leaderstats.Money.Value <= price then
        print("Not Enough")

elseif max == false then
humanoid.WalkSpeed = speed
speed = speed + 1
price = price + 25
player.leaderstats.Money.Value = player.leaderstats.Money.Value - price
wait(2)
end
end
end)
