Jane,The best way to get things into the order you'd like is to rename the files. For example, if you want the Prologue first, then hit return when that file is selected, press the space bar once then type Prologue. that will place it at the beginning. For the chapters, you would need to name them Chapter 01 (that is zero one), chapter 02 (that is zero two) and so on. Hope this was what you were looking for.
