Creating tabs with nested ACFs 3 levels

Hoping someone on here can help me. I have created a tab menu with a repeater field that should display in the tab pane. It does work and I can see the data with the inspector but nothing is displaying on the web page. Any ideas?

`if( have_rows(‘logiciels’) ):
$i = 1; // Set the increment variable

echo ‘<ul class=”nav nav-tabs” id=”myTab” role=”tablist”>’;

// loop through the rows of data for the tab header
while ( have_rows(‘logiciels’) ) : the_row();
$header = get_sub_field(‘logiciel_type’);
?>

<li class=”nav-item”>
” id=”<?php echo sanitize_title($header); ?>-tab” data-toggle=”tab” href=”#<?php echo sanitize_title($header); ?>” role=”tab” aria-controls=”<?php echo sanitize_title($header); ?>” aria-selected=”true”><?php echo $header; ?>

<?php $i++; // Increment the increment variable

endwhile; //End the loop

echo ‘
<div class=”tab-content” id=”myTabContent”>’;
$i = 1; // Set the increment variable

// loop through the rows of data for the tab content
while ( have_rows(‘logiciels’) ) : the_row();
$header = get_sub_field(‘logiciel_type’);

?>

<div class=”tab-pane fade show <?php if($i == 1) echo ‘active’;?>” id=”<?php echo sanitize_title($header); ?>” role=”tabpanel” aria-labelledby=”<?php echo sanitize_title($header); ?>-tab”><?php
while ( have_rows(‘contenu_type_logiciel’) ) : the_row(); ?>
<div class=”hentry why text-dark”><?php echo get_sub_field(‘titre’);?></div>
<div><?php echo get_sub_field(‘date’); ?></div>
<div>
<?php
$file = get_sub_field(‘fichier_a_telecharger’);
echo $file;
if ($file):

$filesize = $file[‘filesize’];
$link = $file[‘link’];
?>
“>télécharger
<?php endif; ?>
<?php endwhile; //End the loop ?></div>

<?php $i++; // Increment the increment variable

endwhile; //End the loop

echo ‘</div>’;

else :

// no rows found

endif;
