phtml block is not getting displayed in cms page
{{block type="catalog/product_list" name="home.catalog.product.list" alias="products_homepage" category_id="4" template="catalog/product/list.phtml"}}.
i am using magento ver 1.9 and am trying to call the above phtml file in a cms page. magento is not giving any error neither it is displaying the contents of the file. I realized this is happening with both my magento instances whereas <blocks></blocks> are working fine. Can anyone help me understand what is happening or what i have to do to display the phtml files in cms pages. Its urgent.
thanks in advance
