Create A New Layout Block Magento Basket Page

Question

So I want to change a code block (discount vouchers) on the cart page. I need to create a new file to style this block.

The existing layout file (XML) has the following code:

<checkout_cart_index>
 <reference name="checkout.cart.coupon">
 <action method="setTemplate">
 <template>rewardpoints/coupons.phtml</template>
 </action>
 <block type="rewardpoints/coupon" name="checkout_cart_coupon_normal" as="coupon_points" template="rewardpoints/reward_coupon.phtml">
 <block type="checkout/cart_coupon" name="checkout_cart_coupon_reward" as="coupon_original" template="checkout/cart/coupon.phtml"/>
 </block>
 </reference>
</checkout_cart_index>

I'm trying to copy that by adding the following below that:

 <reference name="checkout.cart.coupon.short">
 <action method="setTemplate">
 <template>rewardpoints/coupons_short.phtml</template>
 </action>
 <block type="rewardpoints/coupon" name="cart_coupon_points_short" as="coupon_points_short" template="rewardpoints/reward_coupon_short.phtml">
 <block type="checkout/cart_coupon" name="cart_coupon_points_cart" as="coupon_points_cart" template="checkout/cart/coupon_cart.phtml"/>
 </block>
 </reference> 

I have created the new phtml files and for now, they contain exactly the same data. There are no ID conflicts.

These are being called with the $this->getChildHtml('coupon_points_short'); code. Needless to say, the page is just empty. White. Nothing.

Could someone please advise me how to proceed.

• Jongosi: I just cracked it! This file was actually correct, but it was referenced higher up in another layout template (checkout.xml) first. I put a block in there: <block type="checkout/cart_coupon" name="checkout.cart.coupon.short" as="coupon_short" template="checkout/cart/coupon_short.phtml"/> ...now it works like a charm. Thanks for taking a look.
