Ah, that was it. For some reason I didn't even look at those 3 fields to the right- the top two were in green, so i just assumed they were something Calibre used, and not for me. Being new to Calibre, I have a habit of being afraid to touch anything I'm not sure about. In retrospect, that was pretty cut and dry; I don't know how i missed it, but thank you so much for clearing it up. And thank you for being so nice about it.
