Problem with creating an ePUB...
Having recently revised an existing paper book of mine I decided to create an ePUB version. Using the .docx file of the the interior content I assigned a Heading 1 style to the title, copyright registration, etc. Like wise, I assigned a Heading 2 style to each chapter number. By the way, I'm using LibreOffice Writer as my word processor.
After saving the .docx file I proceeded to follow the steps to create an ePUB. After uploading the .docx file I proceeded to create the ePUB file. My attempt, however, was unsuccessful.
Instead, I received the following error message: "There do not appear to be any chapters in your table of contents. This suggests that you need to properly set chapter divisions in your document."
I believe the instructions for creating an ePUB file stated that you are not to create the Table of Contents yourself; that will be done as part of the conversion process. So, can anyone tell me what's going on here, in particular why the ePUB converter is not seeing my headings, and how to successfully produce an ePUB file? Thanks.
