GUI Hat Shop?

I am creating a GUI hat shop, this code is positioned inside the GUI button within frame within the GUI. The script does not throw a error but does not work either.

wait(0.5)
player = script.Parent.Parent.Parent.Parent.Parent
money = player.leaderstats.Wins
price = 0


function buy()
if money.Value >= price then
        if (player:findFirstChild("Humanoid") ~= nil and debounce == true) then
        debounce = false
        h = Instance.new("Hat")
        p = Instance.new("Part")
        h.Name = "SidesweptBangsBrown"
        p.Parent = h
        p.Position = player:findFirstChild("Head").Position
        p.Name = "Handle" 
        p.formFactor = script.Parent.formFactor
        p.Size = Vector3.new(1, 1, 1) 
        p.BottomSurface = 0 
        p.TopSurface = 0 
        p.Locked = true 
        game.Workspace.THat1.Mesh:clone().Parent = p
        h.Parent = player
        h.AttachmentForward = Vector3.new(0.196, -0, -0.981)
        h.AttachmentPos = Vector3.new(0.12, 0.3, -0.07)
        h.AttachmentRight = Vector3.new(0.981, 0, 0.196)
        h.AttachmentUp = Vector3.new(0, 1, -0)
        wait(5)
        debounce = true
    end


end
end
script.Parent.MouseButton1Down:connect(buy)
