I facing a problem here, my repeater having one layer but with few sub domain inside it, also I set one of the sub domain can be select multiple times, I tried to use get get_sub_field() but it always displaying “Array” instead of displaying all of the selection while I turned on the “multiple selection”.

Here’s the code (researches is the layer field name and slug is the one I mentioned with multiple selection):

` <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php

if(have_rows(‘researches’)):while(have_rows(‘researches’)):the_row();

$array = get_sub_field(‘slug’);
?>
<span> <?php echo $array; ?> </span>

<?php endwhile;
endif; ?>
<?php endwhile;
endif; ?>`

I attached my setting below for better overall picture,
I hope someone can helps, thanks!
