3. Now, we need to open the local.xml file and find the <catalog_product_view> product view handle (for your reference, this handle is defined first inside the catalog.xml file of the base theme in app/design/frontend/base/default/layout) and inside it, in <reference name="content">, add the following code that will declare a core/template block to be displayed on the product page:

   <reference name="content">
