Nothing displayed if the top level category clicked

[RoPey]

Hi
I reckon I must be missing something very obvious here, but all the searches I've done have provided no help.
I am using flyout menus for the categories and if the user clicks on any of the top level categories, rather than selecting the bottom level where the products are, they reach an empty page.
http://www.motoskinzfx.co.uk/shop
So, if the user clicks on Graphics, or on Honda under Graphics, they see nothing at all.
I would like to show a list of links to the next level down so that, most importantly, if the flyouts don't work for some reason there is still a navigable way through the site, and also so that users won't just see empty pages.

Any help gratefully received.

What happens if you switch to Classic Template ... do things start working correctly on the navigation?

Yes Ajeh, it does work. So I've broken something with my template. Can you give me a clue where to start looking?
Thanks

Actually, your question gave me a clue and I've fixed it. For some reason back when I first started this project, absolutely new to Zencart, I managed to comment out the wrong bit of code in my custom template.
Thank you for the lead!
