My Localscript for a SurfaceGUI textbutton isn't working. Suggestions?

buy=script.Parent
wep=game.ServerStorage["AK-47"]
price=script.Parent.IntValue.Value

buy.MouseButton1Down:connect(function()
	local user=game.Players.LocalPlayer
	if user.leaderstats.Caps.Value>=price then
		user.leaderstats.Caps.Value=user.leaderstats.Caps.Value-price
		local wepa=wep:Clone()
		wepa.Parent=user.Backpack
	end
end)

There is a tool in serverstorage named AK-47. The localscript is nested in the text button. There is an IntValue in the TextButton. Caps is an IntValue.

Hope this helps.
