Adding a block snippet to a static block not working

Built a module with one block - List.php

class Pts_HireCms_Block_List extends Mage_Core_Block_Template { protected $productRange; public function loadCollection($productRange) { return Mage::getModel('hirecms/hire') ->getCollection() ->addFieldToFilter('product_range', $productRange) ->setOrder('position', 'asc'); } public function getHireProd() { return $this->loadCollection('Hire Prods'); } public function getNonHireProds() { return $this->loadCollection('Non Hire Prods'); } } 

Then I have a theme xml file of hirecms.xml:

<?xml version="1.0"?> <layout version="0.1.0"> <default> <reference name="root"> <block type="hirecms/list" name="hireProd" template="hirecms/hire-prod.phtml" /> <block type="hirecms/list" name="nonHireProd" template="hirecms/non-hire-prod.phtml" /> </reference> </default> </layout> 

and i've added:

{{block type="hirecms/list" template="hirecms/hire-prod.phtml"}} 

to a static block, then on a category i've set display mode = static block only and cms block = to the one ive created.

However when i visit the route, the page loads but my block {{block type="hirecms/list" template="hirecms/hire-prod.phtml"}} is not being called.

Any ideas why?

I have this working perfectly on my local site, and the code has been pushed using github so no amendments along the way.

Thanks
