Magento – Fixing Issues with Calling phtml Files in Static Blocks

in cart page , we implemented a feature of finding shipping charges using this file : app/design/frontend/default/theme/template/checkout/cart/shipping.phtml

I need the same feature in cart page….

cart page file : app/design/frontend/default/theme/template/checkout/cart/item/default.phtml file.

so i created static block with identifier : "delivery" , than inserted following code :

{{block type="core/template" template="checkout/cart/shipping.phtml"}}

than in default.phtml file, i used this code :

<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('delivery')->toHtml();  ?> 

but its not working for me. shipping.phtml code
