Possible to Re-Use Magic Fields?

Hello I’m using magic fields to display content in separate boxes on my sites homepage. I want these boxes to be brought into my sidebar further into the site.

Can anyone tell me how to do this without duplicating the content?

My understanding is the magic boxes uses custom fields which are attributed to a certain page. So I should be able to just call those custom fields but I’m getting very confused.

I feel like I’m near with <?php echo get_post_meta('22', 'blue_title', $single=true);?>

’22’ being the page id the custom field is on and ‘blue_title’ being the key. But it’s not displaying anything – Also for this area of the site I’m using pages not posts with might be another problem

Any help really appreciated.
