My shop GUI won't work?

I'm making a shooter, and I'm making a shop. The problem is, whenever I click on the shop item I'm trying to get, I don't get anything. Here's the script for the button:

repeat wait()
    Player = game.Players.LocalPlayer
Button = script.Parent
Item = game.ReplicatedStorage:FindFIrstChild("GravityCoil")
Cost = 50
Money = Player.leaderstats.Money    
until

Button.MouseButton1Down:connect(function(purchase)
    if Money.Value > (Cost - 1) then
        Money.Value = Money.Value - Cost 
        local a = Item:Clone()
        a.Parent = Player.Backpack
        local b = Item:Clone()
        b.Parent = Player.StarterGear
    end
end)

This is the script for the leaderboard I was using (I gave myself 50 money)

game.Players.PlayerAdded:connect(function(p)
    local stats = Instance.new("IntValue", p)
    stats.Name = ("leaderstats")

    local money = Instance.new("IntValue", stats)
    money.Name = "Money"
    money.Value = 50
end)

Thanks in advance!
