collections/show code help

I'm trying to make my collections/show pages ( have the same look and functionality as /items (

I was able to copy & paste and tweak the code a bit to come up with what I've done so far, but am not seeing the pagination (and therefore the ability to view more than 10 items in each collection).

I'm guessing there is something that I'm overlooking in the php but I've been looking at it too long and can't figure it out. Any thoughts on how to make
<div id="pagination-top" class="pagination"><?php echo pagination_links($options = array()); ?></div> appear on collections/show?
