FWIW, this is the statement that I was responding to when I posted the link:

Within the link this is the statement I thought "may help" the OP:

"The most common file format for an e-book is Adobe Acrobat PDF. You'll be doing the actual "design" of your book in your word-processing program, however. (If you have a complex design that includes lots of illustrations, you may wish to use a desktop publishing program such as Pagemaker or Quark; however, that's beyond the scope of this article.) Since Word is the most commonly used wordprocessing program (and the program in which most e-publishers will expect your document), this column will focus on formatting in Word."

Beyond that, if it did not help...so be it!

I am done...
