Hi,
My first solution is incorrect ; with the second solution, I don't
understand why the first chapter is not numbered while the second is with
number 1.
Thanks.

Hi, For my book, the header for each chapter should be like the attached image. I don't know if I am using the best method, but the result looks like what I want. Nevertheless, I am having some problems : 1. the header appears on each page ; 2. the title of the chapter should not appear in the body of the text. Thanks for your help. Fabrice
