XML : how to add copy of block "discount" in checkout magento

I need to add block (copy of block discount in shoppcard) under existing block. I have some code, but I am nubby and don't know what I must to add in my config.xml and phtml file. So, i created file config.xml(still empty) in directory local/Andrew/Catrt2/ect And to add layuot and template in directories frontend/andrew/default/layout/coupon.xml with code

  <?xml version="1.0" ?>   <!-- Root node for Magento layout configuration -->    <layout version="0.1.0">     <default>      <reference name="checkout.cart">          <block type="andrew/cart2_coupon2" name="checkout.cart2.coupon2"   as="coupon2" template="coupon2/view.phtml" after="checkout/cart/coupon"/>      </reference>     </default>    </layout>
