Thanks mrmikel. I use the onboard styles from Word, and I've been exporting as docx, since Calibre can now convert those. I've also noticed Hitch and her comments. She even lives in the same city, so I just may give her a call.
I think I got the add-in working, but the end result I got had tons of <span> tags, and commentary in it. I've got the Calibre CSS figured out, and I'm going to go along with it. I'm reading "ePub Straight to the Point" right now, so here's crossed fingers that I can finally get something working.
Thanks again for the help.
