editing boxes/categories.php


Sketchy

Recommended Posts

Hey, I'm a oscommerce novice trying to strip the code from boxes/categories.php so only the base level categories are displayed.

 

I have somehow achieved the effect I want in the following code but I'm sure there is some superfluous code left over that is just adding clutter.

 

Can anybody help me eliminate the dead code please?

 

Many Thanks :wink:
