title: Magento ajax add to cart result in popup box when we click on add to cart button
body: <p>I have a task like; In magento, when we click on add to cart button, a popup
  box has to be displayed and in that it has to display a text like
  'has been added to cart' and also with two buttons like
  continue shopping and proceed to checkout. So for this I have taken VS-Ajax
  add to cart extension, but popup is not displaying. This everything has to
  be done by Ajax functionality..</p>
  
  <p>So how can I achieve this??</p>
