title: Missing amount and order summary in PayPal Express Checkout
body: <p>I have integrated paypal into codeigniter with paypal_helper (didn't rememeber where I found it, but it is a slightly rewritten version of Paypals original code for express checkout. I try calling this function, </p>
  
  <blockquote>
    <p>CallShortcutExpressCheckout( $paymentAmount, $currencyCodeType,
    $paymentType, $returnURL, $cancelURL)</p>
  </blockquote>
  
  <p>sending $paymentAmount as int, $currencyCodeType as "NOK" and $paymentType as "Sale".</p>
  
  <p>Both in Sandbox and live, no amount appears on the paypal site...</p>
  
  <p>What could be wrong?</p>
  
  <p>Edit, to further explain my process. I use this, mostly as specified in the <a href="https://www.paypal-labs.com/integrationwizard/ecpaypal/cart.php" rel="noreferrer">https://www.paypal-labs.com/integrationwizard/ecpaypal/cart.php</a>. This should be doable without the form? The paymentAmount could be sent as a standard variable, when calling the function CallShortcutExpressCheckout?:</p>
  
  <pre><code>$resArray = CallShortcutExpressCheckout ($paymentAmount, $currencyCodeType, $paymentType, $returnURL, $cancelURL);
  $ack = strtoupper($resArray["ACK"]);
  if($ack=="SUCCESS" || $ack=="SUCCESSWITHWARNING")
  {
      RedirectToPayPal ( $resArray["TOKEN"] );
  } 
  else  
  {
      //Display a user friendly Error on the page using any of the following error information returned by PayPal
      $ErrorCode = urldecode($resArray["L_ERRORCODE0"]);
      $ErrorShortMsg = urldecode($resArray["L_SHORTMESSAGE0"]);
      $ErrorLongMsg = urldecode($resArray["L_LONGMESSAGE0"]);
      $ErrorSeverityCode = urldecode($resArray["L_SEVERITYCODE0"]);
  
      echo "SetExpressCheckout API call failed. ";
      echo "Detailed Error Message: " . $ErrorLongMsg;
      echo "Short Error Message: " . $ErrorShortMsg;
      echo "Error Code: " . $ErrorCode;
      echo "Error Severity Code: " . $ErrorSeverityCode;
  }
  </code></pre>
  
  <p>The token is saved in a database. The user gets redirected to Paypal, where no amount is listed.</p>
