Money reset script will not reset player money why?

local player = game.Players.LocalPlayer
repeat wait()
until player:FindFirstChild("leaderstats").Money.Value >= 7000000
if player:FindFirstChild("leaderstats").Money.Value >= 7000000 then
	local m = Instance.new("Message")
	m.Text = "Stats Have Been Reset"
	m.Parent = player.PlayerGui
	wait(5)
	m:Destroy()
	player:FindFirstChild("leaderstats").Money.Value = 0
	script.Disabled = true
end
