[TYPO3-templavoila] repeating elements do not render

[John Nicholas]

I am trying to mimic the repeating elements tutorial but with divs. This 
is my source html:

<div class="productgallery">
<div class="productgallery_overview">Description of content </div>
<div class="productgallery_images">
<div class="productgallery_images_head">Title of Gallery</div>
<div class="productgallery_images_cont">
<div class="productgallery_images_thumb">
<a href="#"><img src="images/gallerythumbnail.jpg" width="109" 
height="109" /></a>
<div class="productgallery_images_label">Image Name</div></div>
<div class="galleryclear"></div>
</div>
<div class="productgallery_images_foot"></div>
</div>
</div>

The "productgallery_images_cont" is mapped as the section container and 
the "productgallery_images_thumb" is the block that should repeat with 
the obvious fields inside. The interface shows properly in the BE and I 
can add several gallery items. But when the frontend view is rendered it 
just looks like this:

<div class="productgallery">
<div class="productgallery_overview"><p class="bodytext"><strong>Durable 
Product Labels</strong> <br />Lorem ipsum dolor sit amet, consectetuer 
adipiscing elit. Nam et felis. Pellentesque leo pede, molestie 
adipiscing, consectetuer non, dictum eget, libero. Mauris vitae massa. 
Aenean ut purus faucibus turpis fringilla volutpat. </p></div>
<div class="productgallery_images">
<div class="productgallery_images_head"><img 
src="typo3temp/GB/b2b37fe2d9.gif" width="249" height="20" border="0" 
alt="" title="" /></div>
<div class="productgallery_images_cont">

</div>
<div class="productgallery_images_foot"></div>
</div>
</div>

I feel like I've tried every variant of mapping the _cont and the 
_images blocks but nothing ever shows inside _cont. Any ideas?
