python:
def evaluate(book, context):
	import os
	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 three section, author, title, format.extension
			# We want to return author/format without the extension
			p = v['path']
			r,f = os.path.split(p)
			format = os.path.splitext(f)[0]
			r,title = os.path.split(r)
			r,author  = os.path.split(r)
			return '/'.join((author, format))
	else:
		return 'title - author'

your code works well also! Thank you for your help.

Yes, there are many great folks there as well. Thanks!

For future reference, the next calibre release (8.7 or a preview) will contain a template function that can do what the python template does.

formats_path_segments(with_author, with_title, with_format, with_ext, sep)
return parts of the path to a book format in the calibre library separated by ``sep``. The parameter ``sep`` should usually be a slash (``'/'``). One use is to be sure that paths generated in Save to disk and Send to device templates are shortened consistently. Another is to be sure the paths on the device match the paths in the calibre library.

See the manual for full documentation.
