// This is what I have to output data from a metabox:

<?php $secondaryContentmb = get_post_meta($post->ID,'_secondary_content',TRUE); ?>
<h3><?php echo $secondaryContentmb['title'];?></h3>
<?php echo $secondaryContentmb['description'];?>

// This is what I'm attempting to do but keep getting a fatal error:

<?php if ($secondaryContentmb->have_fields('description')) : ?>
	<?php $secondaryContentmb = get_post_meta($post->ID,'_secondary_content',TRUE); ?>
	<h3><?php echo $secondaryContentmb['title'];?></h3>
	<?php echo $secondaryContentmb['description'];?>
<?php endif; ?>

// I've tried while instead of if but no win.
