Why won't my script make a hat attach to the players head?

player = game.Players.LocalPlayer
h = player.Character.Head
script.Parent.MouseButton1Down:connect(function()
    h.face:Destroy()
    for _,v in pairs(player.Character:GetChildren()) do
        if v.ClassName == "Hat" then
            v:Destroy()
            game.ServerStorage.NatsuHair1:clone().Parent = player.Character
            game.ServerStorage.NatsuHair2:clone().Parent = player.Character
        end
    end
