                            if( is_numeric( $nd_booking_trip_price ) ){

                                $nd_booking_trip_price = (int) $nd_booking_trip_price + (int) nd_booking_get_final_price($nd_booking_id,$nd_booking_date_cicle);

                                $nd_booking_date_cicle = date('Y/m/d', strtotime($nd_booking_date_cicle.' + 1 days'));

                                $nd_booking_index++;

                            }
