Hi,

I have to write a book :
on the even pages at the bottom and on the left : the page number, a vertical line and the number of the chapter preceded by the text "Chapter" ;

on the odd pages at the bottom and on the right : the title of the chapter, a line vertical and page number.

Thanks for your help.

Fabrice
