I'm able to get the page-template working up to a point:
a) The books pages appear properly with a reserved space for a header
b) I can assign text to the header region
c) Said text only appears on the first page, not on subsequent pages made with the same template and page master
I can put the fragments I used to get this much working on the thread if there's interest. Does anyone know to make the text appear on all pages made from the same template?
