Showing a sub field if it exists

	<div class="credits-container">

		<section class="entry-content content-projects" itemprop="articleBody">

				<?php if(get_field('credit')): ?>

					<h2 class="centre credits">Credits</h2>

					<?php while(has_sub_field('credit')): ?>

						<p class="centre credits">
						
							<?php the_sub_field('role'); ?>: 

							<a href="">
								<?php the_sub_field('name'); ?>
							</a>
						
					<?php endwhile; ?>

				<?php endif; ?>

		</section>

	</div>

I am using the above code to display a repeater that has 3 sub fields; Role, Name and Link.

There won’t always be a link, which is a URL that will be wrapped around the name.

I am struggling to get the link to show if there is one, as I know my current code just displays the link no matter what. I had tried something but to no avail, so any help would be much appreciated.

Thank you
Mark

$name = get_sub_field('name');
if (get_sub_field('link')) {
  ?>
    <a href="<?php the_sub_field('link'); ?>"><?php echo $name; ?></a>
  <?php 
} else {
  echo $name;
}
