Hi @bluebirdhaze
You can use a simple counter to output the row number dynamically within a repeater field like so:
<?php if( have_rows('repeater') ): $i = 0; ?>
<ul class="slides">
<?php while( have_rows('repeater') ): the_row(); $i++; ?>
<li>
<?php echo $i ?>. <?php the_sub_field('style'); ?>
</li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
Thanks
