I bet that your code is working. It is doing exactly what it is supposed to do. It may not be doing what you want it to do, but...

If you want help, you must ask in a better way. Read the forum rules. Use code tags. Explain what happens when your sketch runs. Explain what you want to happen. Give a schematic, even hand-drawn, or a clear picture.
