Display Subcategories in index

[Enahs]

Hi,

Perhaps somebody can help noob me out.
I am trying to use the following script:

I have it working and modified some. But I am trying to get it on the main page to display the subcategories for each category.

It seems like it should be easy, I just suck apparently.

What do you have so far? Are you getting any errors?

Forgive me, my wording was probably confusing.

I have it working and modified in the other ways I need successfully. I am just not sure how to approach (or even code) this aspect of displaying the subcategories on the main index as well.
