Category News Links

Hi,

I am having a few problems customising the loop to display posts with links that go to that article within the category of that article.

I have tried a link like:
index.php?cat=20#post-222

The problem I am having is this only works if the post is on the first page of the category.

Is there any way of getting the paged value for a particular postid in a particular category.

Any suggestions on how to solve this problem are greatly appreciated.

Regards,
Zac
