  <p>To be more specific, i'm using this library - <a href="https://github.com/orderly/codeigniter-paypal-ipn" rel="nofollow">https://github.com/orderly/codeigniter-paypal-ipn</a> and i'm logging the variables and all the <code>option_name</code> and <code>option_selection</code> vars are blank</p>
