I'm trying to get fancyheaders in a book, with this preamble \fancyhead[RO,LE]{\thepage} \fancyhead[LO,RE]{\rightmark}
I get the SAME kind of headers on both odd and even pages. The page number is in the righthand corner, and the sectionnumber+name is in the lefthand corner. That is what I want for the odd pages, but for the even pages I want the page number to the left, and section the right. What's wrong?
