WordPress Passing Categories in posts

Hi all,

Im hoping someone can help me here as its been driving me up the wall the last 2 days!

Ok here is my example in which im hoping someone can point me in the right direction – http://lifted-radio.co.uk/podcasts/?p=26

You will notice there is an RSS feed icon for this post. The idea is when someone clicks that icon Itunes will open so that specific person can subscribe to that specific Podcasts/RSS.

The situation is, each artisit is going to have their own specific feed so people can subscribe to that specific person.

Im having kittens here trying to sort this out so it works!

Currently its displaying all feeds like this – itpc://lifted-radio.co.uk/podcasts/?cat=&feed=rss2 as you can see the CAT is blank.

Here is where things get confusing. If you visit this page – http://lifted-radio.co.uk/podcasts/?cat=16 – The CAT is appearing. Im using the below code, can someone make a suggestion.

Thanks in advance.
Regards
Tom
