I don't think I can demonstrate my 'newbie-ness' any better.
I have all the chapters in one large directory and attach the appropriate chapter when I upload. However, despite naming the chapter Book 2 - chapter 3 the SOL system uses the name of the file which is from the master list. So I have spent this morning creating separate book folders so on Tuesday the update should say Chapter 4 not chapter 23.
I now have to go back into the system and fix the first three chapters of Book 2 (as well as mark Book 1 complete at Chapter 19).
I just hope I don't screw everything up and make it worse.....
