Ummm.. ok. So I haven't been able to figure out how or if the subcategory siblings data exists already.. somewhere. I want to provide a select menu which contains all the sibling subcategories, but on the subcategory pages.. I am able to locate the data if I am on the parent category page.

Am I going to need to make my own function to get this data?

If so, is there a tutorial or thread that explains the hierarchy (not sure this is the right word)?

From looking through the php files, I see the functions are in the /include/func files (duh) and I understand the root level php files passes values into Smarty, which is then used in the .tpl files... is it alright to call a function from the root php files or do I need another level in there?
