	from calibre.library import current_library_path

	fmt_metadata = book.get('format_metadata')
	if fmt_metadata:
		for v in fmt_metadata.values():
			# A calibre format name is roughly "author/title (id)/title - author.extension"
			# We want to return the last segment, stripping off the author and title 
			# directory names and the extension, leaving just the basename of the book file
			f = v['path']
			return f[f.rfind(os.sep)+1:f.rfind('.')] 
	else:
		raise ValueError('Book "{}" has no formats'.format(book.title))

Thanks chaley for your assistance,
I really appreciate it. The problem is that I am not very technical. Would it be too much to ask for more detailed instructions? I have tried entering the code in the template editor, but it produces an error. What steps am I missing?
