My first Zen Cart attempt....www.dimplesdaisysanddandelions.co.uk/index.php

The sub categories are showing on the drop down menu LH side BUT they are also showing on the main page.

How do I stop it doing that? - I can only see an option Configuration>Layout settings for not showing CATEGORIES on the main page. Have the manual but cant see how to do this for sub-categories, as I dont want them in both places!

ALso....how do I get a line to show between the products on eg
DIESEL/GIRLS/2-10, where he photos nearly touch?

If I look at all products or new products thats how I want it but cant see what to change!!

thanks
