Yup, that did it. I did have to change my 'undefined' check to make sure it worked:

program:

percent = raw_field('#percentread', -1);

	if 'dnf' inlist_field '#admintags'
	then 'didnotfinish'

	elif (percent >=#1 && percent <=#99||$$#lastread != 'None' && percent ==#0)
	then 'currentlyreading' 

	elif $#readinglist=='To Be Read' && percent ==#0
	then 'toberead' 

	elif readgoal() inlist $#admintags && percent ==#0
	then 'backlog' 

	elif percent >=#100
	then 'read' 

	elif percent >=#0
	then 'unread' 

	elif $$#percentread == 'None'
	then 'undefined' 

	fi
