I need to return two fields

<?php
Include ("databaselogin.php");

//get the customer's villa name and determine if it is an add-on order
$thevilla = $this->co_villa; ********help me with this line please*********
$addonorder = $this->co_addon;********help me with this line please*********


if ($addonorder)
  {
  $deliveryarea = 3;
  }
else
  {
$theSQL = "SELECT ib_villas.villa_deliverylocation
FROM jos_hikashop_zone INNER JOIN ib_villas ON jos_hikashop_zone.zone_id = ib_villas.villa_zone
WHERE (((jos_hikashop_zone.zone_type)='ship') AND ((jos_hikashop_zone.zone_namekey)= '" . $thevilla . "'))";

$query = mysql_query($theSQL);
while ($result = mysql_fetch_array($query)) {
           $deliveryarea =  $result["villa_deliverylocation"];
  }
  }


//at this point the delivery should be 1,2,or 3 depending on the location of the villa and if this is an add-on order
$this->shipping_id  == $deliveryarea;********help me with this line please*********

?>

<?php
Include ("databaselogin.php");
$app =& JFactory::getApplication();
$order = $app->getUserState( HIKASHOP_COMPONENT.'.checkout_fields',null);


//get the customer's villa name
$thevilla = $order->co_villa;
$addonorder = $order->co_addon;


if ($addonorder)
  {
  $deliveryarea = 3;
  }
else
  {
$theSQL = "SELECT ib_villas.villa_deliverylocation

// the following line successfully returns a 1,2,or 3
echo $deliveryarea;

// the following lines do not set the shipping_id to 1,2, or 3
