I apologize if this is already in these forums. I have been searching both here and online for over 3 hours and have had no luck in finding an answer.

So, I want to change/add to the text shown on the Calibre generated covers. I can get the text to work if I use the "standard" fields such as title, author, languages, publisher, etc. I cannot get anything to work if I try to use custom columns/fields.

For example, if I put in {title:lowercase()} it works. If I put in {#fandom:lowercase()} or {fandom:lowercase()} it comes up with EXCEPTION: Value: unknown field fandom. This would lead me to believe that I need to do something different for a custom field, but I have absolutely no clue what I need to do.

(#fandom was just an example. I have tried all of my custom column names in case type of field mattered. Every field gave the same error.)

I know a little java programming, but nothing in python. Anything you guys can help with is appreciated. Thanks!
