Creating 5 page trial for pdf file

Hi guys,
I am new to this and trying to create 2 ebooks from pdf files. I seem to have most things figured out. But I am having some issues creating a trial version that changes to full version once registered. See screenshot for my security settings. It seems to work for one ebook but not the one shown.

You should modify your Registered 1 certificate and condition Always. Always means that all PDF will be limited to 5 pages, even if your users purchased the registered edition.
For your Registered 1 certificate, create a condition “If Trial” and add a limitation to 5 pages.
