Maker sure that works for both.

If not, use:

Code:
        if ($uspsQuote['Number'] == -2147219085) {
          $this->quotes = array('module' => $this->title,
                                'error' => 'NO OPTIONS INSTALLED: ' . $uspsQuote['error']);
        } else {
//          $this->quotes = array('module' => $this->title,
//                                'error' => $uspsQuote['error']);
        }
        return $this->quotes;
