Adding Gallery Album to Blog post

I managed to get the gallery to output, but it's not getting the correct gallery - it just returns the first gallery every time no matter what is selected. I turned on debugging and I see this line in the SQL:

SELECT * FROM perch2_gallery_albums WHERE albumSlug= 'bali-food-safari'

That albumSlug is the same for all blogs even though different albums have been selected via the albumlist selector.

I assume this means this line is incorrect?

$albumSlug = $album[0]['album']['albumSlug'];

This is the array output...

Just 1 blog post. This is the code on the single blog page...

<div class="content-main-inner">
    <?php perch_blog_post(perch_get('s')); ?>
    <?php
        $album = perch_blog_custom(array('skip-template'=>true));
        if (is_array($album)) {
            // ['album'] is the ID of the field to get the slug from
            $albumSlug = $album[0]['album']['albumSlug'];
            perch_gallery_album($albumSlug);
        }
    ?>
    <?php perch_blog_post_tags(perch_get('s'), 'post_tag_link.html'); ?>
</div>

Actually, I got it working using the following. Is there anything wrong with this method?

$blog_album = perch_blog_post_field(perch_get('s'), 'album', true);
perch_gallery_album($blog_album);
