Trying to pull custom field template into post previews

[amidigital]

I am using this CFT plugin.

It works fine inside the post and pages.

But I want the data to appear on the home page at the bottom of each article.

This is the code in the function.php where the post previews are generated.

<?php $miles = htmlspecialchars(get_post_meta($post->ID, "miles", true));
?>

<?php if ($miles != "") {
    echo '<h3 class="summary-deck">' . $miles . '</h3>';
}
?>

</article>

Do you know why this is not working?

Thanks!
