Advanced Custom Filed - how to display field values ​​in a link?

Question

WordPress

I'm trying to display the value of the field in the link:
I sold it and so

<a href="tel:<?= get_field('nomer_telefona'); ?>">[acf field="nomer_telefona"]</a>
 и <a href="tel:<?= the_field('nomer_telefona'); ?>">[acf field="nomer_telefona"]</a>

Displayed just a link does not display the value of the field, but only get_field('nomer_telefona'), the shortcode works adequately.

Answer 1

<?php echo get_field('nomer_telefona'); ?>
