Greetings!
I'm trying to do a new category for my collection: "Year Published".
I don't know how to do it. I got error when I tried, but I did manage to make a 'genre' -category.
- It should get the values from Published -field, if one exists.
- No need to have month / day.
I'd like it to look like this:
>Year
> ??? [No year found]
> ...
> 1980
> 1981
> ...
> 2020
> $Author
Is this doable? Thanks.
