Content Organization - Categories and Child Categories

Hi all,

Just a quick newbie question here... I've just switched to Drupal and am loving it but am having a little difficulty grasping a few things.

One major problem I have been unable to solve through forum searches etc is how to get categories to display their child categories
e.g. The website im working on is for a not-for-profit organization about epilepsy so the intended site structure is as follows:

Site Map

Home
>About Epilepsy
>What is epilepsy
>Epileptic seizures
>Non-epileptic seizures
>Auras
>Syndromes
>...
>Living with epilepsy
>Alcohol
>Alternative Therapies
>Driving
>Employment
>...
>Our programs
>Adult Programs
>Children's Programs
>Contact us

etc...

Now when I go to the taxonomy section (where i create and organize the categories) I have it arranged like this:

Categories

As the main vocabulary:
About Epilepsy
Our Programs

Terms (inside 'About Epilepsy' category)

(em)About Epilepsy(em)
--What is epilepsy
--Living With epilepsy

As you can see I've created the About Epilepsy Twice first on the main categories page as a vocabulary and secondly inside the vocabulary as a term. The reason i did this is because you cant make a page from the vocabulary item and only from a term inside it. The two main sections 'what is epilepsy' and 'living with epilepsy' are set in hierarchy as children to the about epilepsy term.

Now what I expect when one clicks on the About epilepsy term (in italics above) a page would appear displaying all of the subcategories but when I click on that link i just get a page saying "There are currently no posts in this category." How can I get that page to show all of the child terms?

I am using pathauto if that makes a difference

Sorry I hope what I've said makes sense to someone as I'm at a loss on what to do here... Perhaps I'm not organizing my content in the most efficient way if anyone has any suggestions or can help me solve this I would greatly appreciate the help... Thanks everyone
