Page title

I am trying to add a text nav tree manually – I can’t figure out the xainoo plugin. I’m using Wp 1.5. What I’d like is:

Home > Category > Page title

<small>?page_id=5″>Home > <?php the_category(); ?> ><?php the_title(); ?></small>

However, nothing shows. Am I using the correct calls? Many thanks in advance.
