Also, unrelated to the above error:

Is it possible to put a strcat inside a first_non_empty? For icon_fanfics shared template, I want to display multiple icons, but if none exist then use a placeholder. This gave me an error:

Code:

program:

first_non_empty(
   strcat
   (
		if "^foo$" inlist $#taglike then 'foo.png:' fi,		
		if "^bar$" inlist $#taglike then 'bar.png:' fi,
		if "^foobar$" inlist $#taglike then 'foobar.png:' fi,
   )
   if $#taglike then 'placeholder.png' fi 
)

I considered a list_difference (I use one for icons_formats) but I have close to 50 entries!

EDIT: I found a very weird workaround that maybe only works because it's a shared template. I put this in column rules/emblems:

Code:

program:

		if icons_fanfic() then icons_fanfic() 
		else 'placeholder.png' fi
