Accordeon and ACFields

Replies: 0

Hello, thank you for your great work.
I try to put advanced custom fields in accordeon codes, but it seems, the div´s are closing in a wrong way, as you can see here

<?php if( get_field('akkordeon') ): ?>
		<?php echo do_shortcode('[accordion clicktoclose="true"]'); ?>
		<?php if( have_rows('reihen') ): ?>
		<?php while(has_sub_field('reihen')): ?>
		<?php
		$akkordeontitelvar = get_sub_field('akkordeontitel');
		echo do_shortcode('[accordion-item title="' . $akkordeontitelvar . '"] ')?>
		<div class="columns">
			<!-- .content-->
		</div>
		<!-- .columns -->
		<?php echo do_shortcode('[/accordion-item] ')?>
		<?php endwhile; ?>
		<?php endif; ?>
		<?php echo do_shortcode('[/accordion] ')?>
<?php endif; ?>

What I am doing wrong, can you help me, please?
Thank you in advance
ll.
