I'm a complete nube in calibre template language.
I'm trying to take the output of the plugin Pagecount which is the number of words in a book and dividing that by 320 which is my words per minute reading rate and output the total number of minutes to read the book into my custom integer col "#minutes"
I don't know how to assign the product of divide(vals, 320); to my custom column #minutes.
program:
col = '#pagecount';
vals = from_selection(col);
'#minutes' = divide(vals, 320);
But I get this result EXCEPTION: Formatter: Expected end of program, found '=' near '#minutes' on line 4
