title: How to add review tab on product view page
body: <p>I am a beginner in Magento. I want to add a Review Tab in product view page.
  Can anyone help me how to do this?</p>
  
  <p>I tried following approach:</p>
  
  <pre><code>&lt;block type="catalog/product_view_tabs" name="product.info.tabs" as="info_tabs" template="catalog/product/view/tabs.phtml"&gt;
                      &lt;!--action method="addTab" translate="title" module="catalog"&gt;&lt;alias&gt;additional&lt;/alias&gt;&lt;title&gt;General Info&lt;/title&gt;&lt;block&gt;catalog/product_view_attributes&lt;/block&gt;&lt;template&gt;catalog/product/view/attributes.phtml&lt;/template&gt;&lt;/action--&gt;
                      &lt;action method="addTab" translate="title" module="catalog"&gt;&lt;alias&gt;description&lt;/alias&gt;&lt;title&gt;Description&lt;/title&gt;&lt;block&gt;catalog/product_view_description&lt;/block&gt;&lt;template&gt;catalog/product/view/description.phtml&lt;/template&gt;&lt;/action&gt;
                      &lt;action method="addTab" translate="title" module="catalog"&gt;&lt;alias&gt;upsell&lt;/alias&gt;&lt;title&gt;Upsell&lt;/title&gt;&lt;block&gt;catalog/product_list_upsell&lt;/block&gt;&lt;template&gt;catalog/product/list/upsell.phtml&lt;/template&gt;&lt;/action&gt;
                      &lt;action method="addTab" translate="title" module="catalog"&gt;&lt;alias&gt;review&lt;/alias&gt;&lt;title&gt;Review&lt;/title&gt;&lt;block&gt;review/product_view_list&lt;/block&gt;&lt;template&gt;review/product/view/list.phtml&lt;/template&gt;&lt;/action&gt;
                      &lt;action method="addTab" translate="title" module="catalog"&gt;&lt;alias&gt;additional&lt;/alias&gt;&lt;title&gt;Additional Information&lt;/title&gt;&lt;block&gt;catalog/product_view_attributes&lt;/block&gt;&lt;template&gt;catalog/product/view/attributes.phtml&lt;/template&gt;&lt;/action&gt;
  
      &lt;/block&gt;
  </code></pre>
  
  <p>Then using <code>echo $this-&gt;getChildHtml('info_tabs');</code>  in view.phtml.</p>
  
  <p>Only description, review and additional information are visible.
  What may be the problem?
  Thanks</p>
