using php (& DW) - trying to update multiple records

Trying to update multiple records - trying to use an array but am in over my head.  here's what i have:

update code:

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}


if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "spec_order")) {
  $updateSQL = sprintf("UPDATE docspec SET order_id=%s WHERE docspec_id=%s",
                       GetSQLValueString($_POST['order_id'], "text"),
                       GetSQLValueString($_POST['docspec_id'], "int"));

  mysql_select_db($database_SCOI2, $SCOI2);
  $Result1 = mysql_query($updateSQL, $SCOI2) or die(mysql_error());

  $updateGoTo = "specialties4.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $updateGoTo .= (strpos($updateGoTo, '?')) ? "&" : "?";
    $updateGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $updateGoTo));
}

body:
