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.
