I'm trying to setup a custom column to download AO3's kudos into and I keep getting the following error message:
I've tried it as an integer column and as a floating point number column but always the same error message. I've tried no number formatting and I've tried {0:,} and {0:f}. I looked at the python documentation page linked in Calibre's custom column setup page but honestly it made zero sense to me.
This is the line I added to my personal.ini under AO3:
kudos=>#kudos
Any idea what I'm doing wrong?
