i am confused with term get_sub_field(‘new_start_dateend_date’));
and
get_sub_field(‘start_date/end_date’) how these values will be displayed ?? are they single value or different values?

if (!empty(get_sub_field('new_start_dateend_date'))) {
                                                $dis_per = get_sub_field('new_discount');
                                                $dateS = explode('-', get_sub_field('new_start_dateend_date'));

and

if (have_rows('small_group_journey', $pid)):
                                    while (have_rows('small_group_journey', $pid)):the_row();
                                        if (!empty(get_sub_field('start_date/end_date'))) {
                                            $dis_per = get_sub_field('journey_discount');
                                            $dateS = explode('-', get_sub_field('start_date/end_date'));
