I have a Samsung Galaxy Note 10.1 (2014) that I'm trying to get files onto. I've defined a couple of custom columns pretty much out of the help pages on the calibre web site

series_stripped: {series:re(^(A|The|An)\s+,)||}
series_initials: {#stripped_series:re(([^\s])[^\s]+(\s|$),\1)}

But when I attempt to "Configure this device" for and use #series_initials in the template, I get an exception

{series:'ifempty($,field('author'))'||/}{#series_initials:|| }{title}
EXCEPTION: Value: unknown field #series_initials

I finally just saved it anyway. It worked.
