ACF Fields not showing up

I’ve been trying to get a CPT archive page to convert to PDF. Basically, i have a CPT acting as a directory with addresses using Advanced Custom Fields, and want to print off a PDF of the archive page that is set up as address labels.

I’ve got it working to the point of showing the post titles in the pdf, but I also need to get the ACF fields showing.

Here’s what’s in my template that needs to print (along with the suggested php codes:

<?php pdf24Plugin_begin(); ?>
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>

<article class="listing">
  <a href="<?php the_permalink(); ?>" class="listing-link">
    <div class="row">

      <div class="col-sm-8 col-xs-12 listing-archive-description">
        <div class="listing-title-desc">
        <?php the_content(); ?>
          <h4><?php the_field('SALUTATION');?> <?php the_field('FIRSTNAME');?> <?php the_title(); ?>...</h4>
          <p><?php the_field('C_STREET');?></p><p> <?php the_field('C_ADDITIONAL');?></p><p> <?php the_field('C_CITY');?>, <?php the_field('C_PROVINCE');?> </p><p> <?php the_field('C_COUNTRY');?> </p><p><?php the_field('C_POSTALCODE');?></p>
        </div>

      </div>

    </div>
  </a>
</article>

<?php endwhile; ?>
<?php pdf24Plugin_end(); ?>

But all i still see is the title. I know in the options i can change the pdf layout, but when i add the required Custom Field elements above, it doesn’t show up.

Any ideas? Am i doing something wrong?
