Great news! It worked on this one book section! So this book is fixed! The same fix did not work on the other three resistant sections, but I am guessing it is because the toc-preface section wasn't the right style for THOSE books. But now I know what to look for and how to search out the right codes for the remaining books! You gave me the right place to look to fix the rest of the problem Hitch! Thanks so much!
Since the problem seemed to stem from me using Calibre to do the last minute things to the book before loading it to the ereader, do you know, can I load it from Sigil? If not, no biggie, I just thought not going through Calibre would have saved some of the headache of the extra styles. Thanks again! You are the best!
