I am creating ebooks from scratch. I have figured out how to set the cover image, create a NCX and have even added a Linked HTML TOC at the beginning of my book. The problem I am running in to is that when I am viewing my book in the Kindle Previewer and I select the Table of Contents button I get the error "Missing Table of Contents, Your book is currently missing a TOC, which allows easy navigation in Kindle books......" Same goes for the Kindle Fire, when I select the TOC button there is no TOC. Does anyone have any insight on how to do this? Maybe a guide. I am not sure if I am suppose to add a TOC to the .opf or where exactly. Any help would be greatly appreciated.
