Hello everyone,

I'm new to this forum so I hope I'm in the good place for this question.

I use the Countpage plugin which displays the number of words of a epub in a custom column called "mots".

What I want to do is to display a fraction of this number in another custom column called "durée" (so I can have the reading time of the book, based on my reading speed)

I read some documentation about the calibre templates and functions and I try a lot, but I can't manage to perform this simple operation. I get an error each time i try.

Can anyone explain to me which syntax to use for this operation?

Thanks you very much

Vianney
