I current have a custom field that is displaying even if there is not data inputted in the meta box when posting.

How do I remove the hr, title, and ul if there is not data input? Here’s the code I have currently to pull in the custom field:
<?php if( have_rows('google_drive_links') ): ?>
<?php while( have_rows('google_drive_links') ): the_row();
// vars
$content = get_sub_field('google_link_name');
$link = get_sub_field('google_link'); ?>
<hr />
<h3>Attachments</h3>
<ul class="google-drive-links">
<li class="google-drive-link-item">
<a target="_blank">"><?php echo $content; ?></a>
</li>
</ul>
<?php endwhile; ?>
<?php endif; ?>
Looks like I had part of my code wrong. Here’s what I’m currently using:
<?php if( have_rows('google_drive_links') ): ?>
<hr />
<h3>Attachments</h3>
<ul class="google-drive-links">
<?php while( have_rows('google_drive_links') ): the_row();
// vars
$content = get_sub_field('google_link_name');
$link = get_sub_field('google_link'); ?>
<li class="google-drive-link-item">
<a target="_blank" href="<?php echo $link; ?>"><?php echo $content; ?></a>
</li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
