Missing GC details on product page
To get gift certificate specific html in your template you need to
have a call like <?php echo $this->getChildHtml('product_type_data');?>
, it could be the case that you don't want
to display this for other product types, so you may wrap it in a conditional statement like:
<?php if ($_product->getTypeId() == 'ugiftcert'): ?>
<?php echo $this->getChildHtml('product_type_data');?>
<?php endif;?>
