Hi @mathieu
In case you are using a repeater, I would recommend that you use a the standard repeater loop to access the repeater rows.
<?php
// check if the repeater field has rows of data
if( have_rows('repeater_field_name') ):
// loop through the rows of data
while ( have_rows('repeater_field_name') ) : the_row();
// display a sub field value
the_sub_field('sub_field_name');
endwhile;
else :
// no rows found
endif;
?>
If you just want the first row, you can introduce custom code to only pick the first row.
I hope this helps.
