Display post by id from custom field

[HelenaB]

Hi all.

I'm trying to display a certain post's title, excerpt, featured image and link after a given page's content.

This works perfectly in the editor itself and in Simple Hooks after_post_content:

[display-posts include_excerpt="true" id="221"  image_size="thumbnail" wrapper="div"]

But I need it to be simpler for the user, so I'd like them to just be able to enter the id of the post they want to appear in a custom field called casestudy - but I'm having trouble getting it to work.

I've tried adding the following via simple hooks in genesis_after_content but if I tick execute PHP and shortcode it lists all posts rather than just one.  If I tick execute PHP it echoes the shortcode exactly as written above so it should be correct?

<?php if( genesis_get_custom_field( 'casestudy' ) ) { ?>
[display-posts include_excerpt="true" id="<?php genesis_custom_field("casestudy" ); ?>" image_size="thumbnail" wrapper="div"]
<?php } ?>

What am I doing wrong?

Thanks in advance

Any suggestions most welcome!
