With one small addition it worked:
if (have_rows('repeater_field')) {
while (have_rows('repeater_field')) {
the_row();
$name = get_sub_field('name_field');
$title = get_sub_field('title_field');
echo $name->name,': ',$title[0]->name;
}
}
Each name may have multiple titles, so would there have to be another loop within to get all of those?
