Hello,
Please run this scripts to understand how evenPage and oddPage options work:
http://pastebin.com/bMwfpVfR
http://pastebin.com/40tm0D84
and open both DOCX.
The oddPage adds a section, where you add text, in the next odd page. And the evenPage adds a section in the next even page.
But it's very important to understand that you can't know if a content fills a whole page, so you don't know if the next page will be an odd or an even page.
Regards.
