As the title says, i want to be able to create and display custom category attributes.

I tried this extension: http://www.magentocommerce.com/magento-connect/manage-category-customer-and-customer-address-attributes.html

And this extension allows me to create the attributes, but I dont know how to display them in my template files. I tried the following code:

<?php echo Mage::getResourceModel('catalog/category')->getAttributeRawValue($_category->getId(), "subtitel", Mage::app()->getStore()->getId()); ?>

but that did not do the trick.

Any suggestions?
