Topic: Shipper Added to Sales Order

OK, I've spent a few hours on this already and can't figure it out.  I've looked at the wiki mentioned previously on this issue and scoured the database and search terms in the forums.

Here is what I have so far.  What should be on the "Shipping Method" line to show the shipper_name?:

case ST_SALESORDER:
            $this->title = ($this->params['print_quote'] ? _("QUOTE") : ($this->formData['prepaid'] ? _("PREPAYMENT ORDER") : _("SALES ORDER ACKNOWLEDGEMENT")));
            $this->formData['document_name'] =_("Order Ackn. No.");
            $this->formData['document_date'] = $this->formData['ord_date'];
            $this->formData['document_number'] = $SysPrefs->print_invoice_no() == 0 && isset($this->formData['reference'])
                ? $this->formData['reference'] : $this->formData['order_no'];
            $this->formData['document_amount'] = $this->formData['order_no'];

            $aux_info = array(
                _("Customer's Reference") => $this->formData["customer_ref"],
                _("Sales Person") => get_salesman_name($this->formData['salesman']),
                _("Shipping Method") => $this->formData['shipper'],
                _("Internal Order No") => $this->formData['order_no'],
                _("Delivery Date") => sql2date($this->formData['delivery_date']),
            );
            break;
