Hi Mike,
Ahhh, sounds like you have created a little problem for yourself
. You do know that rather than including series information in the title there are "other ways" using metadata plugboards to get it sorted on the Kindle? So you don't have to "corrupt" your Calibre title?
Regardless, what you want should be possible with the latest versions of this plugin since we incorporated using the Calibre template engine.
Can you post the URL from your configuration dialog, and the URL that is appearing in the web browser?
