title: Magento - Get session GrandTotal?
body: <p>Right now i am using Mangeto 1.9.1 and i am trying to get the GrandTotal value of the session order in external php file in the main Magento directory.</p>
  
  <p>Here is my php file:</p>
  
  <pre><code>&lt;?php
      error_reporting(E_ALL | E_STRICT);
      $mageFilename = 'app/Mage.php';
      require_once $mageFilename;
      $app = Mage::app('default'); 
      Mage::app();
  
  
      $quote = Mage::getModel('checkout/session')-&gt;getQuote();
      $quoteData= $quote-&gt;getData();
      $grandTotal=$quoteData['grand_total'];
  
  
      echo "Grand: - $grandTotal";
  ?&gt;  
  </code></pre>
  
  <p>But it's not printing the value of the grand total.
  Where is my mistake how i can make this thing work ?</p>
  
  <p>Thanks in advance!</p>
