In case anyone stumbles upon this, I managed to get the code example to work with me…it was just adding ‘option’.
<?php $rows = get_field('the_block', 'option'); $row_count = count($rows); $i = rand(0, $row_count - 1); ?>
<section id="theblock" style="background: url('<?php echo $rows[$i]['block_background']; ?>');">
<div id="theblock-inner" class="container">
<div class="section-title civider">
<h2><?php echo $rows[$i]['block_title']; ?></h2>
<h5 class="subtitle"><?php echo $rows[$i]['block_subtitle']; ?></h5>
</div>
<a href="<?php echo $rows[$i]['block_link_url']; ?>" class="btn"><?php echo $rows[$i]['block_link_text']; ?></a>
</div>
</section>
