I turned on the module title and, yep, I've got items in the category.
I think with the template I'm using, I have to be more selective about which position I'm using for the content to show correctly. The positions I selected were enabled, but it still wasn't showing up. (User error, I'm sure) I changed the module position a couple of times and finally got it to show.
Bottom line-- K2 is great and I just have to fuss with getting these module positions to act right.
THANK YOU!
