International NCX/Hyperlink E book

Hello there I want to ask you a question: what is the format of your e book? It is just chapters etc or does it have a NCX/hyperlink within it? What is NCX? it is the Navigation Control Program. This program enables your ebook to have an hyperlink within it. Right now, Amazon is demanding this from their authors. This is fast becoming the standard in whcih e books are being sold. So, if your e book doesn' t have that, it will be difficult for it to be converted to other reading devices. All my e books are in this format and are rated between 3-5, mostly 4-5 in the international market. see the link as an example of a review You need this package.
