Forgive me for asking this, but can someone help me turn back on the subcategory grid in the center column! I remember somehow disabling it, but now I can not seem to find out how to turn it back on!

What I'm looking to do is list the subcategories in the center column after you click on a top-level category in the left menu. Zen Cart operates like this by default, but somehow I have turned it off. Any suggestions?

Thanks in advance!
