Raymond> I don't know what to do about customize in this case. Oops. I've found that if I do this in customize, I get what I want: Sc Attrib Selection List: * [INS] [DEL] List: String: from Repeat: [INS] [DEL] Cons-cell: Regexp: "\([^ ]+\) \([^ ]+\) (EUS) Choice: [Value Menu] Repeat: [INS] [DEL] Repeat: [INS] [DEL] Lisp expression: let [INS] [DEL] Lisp expression: ((field (sc-mail-field "from"))) [INS] [DEL] Lisp expression: (string-match "\"\\([^ ]+\\) \\([^ ]+\\) (EUS)" field) [INS] [DEL] Lisp expression: (match-string 1 field) [INS] [INS] Hardly intuitive. Is this the way it's supposed to work? It would seem much more intuitive if I could have just entered [INS] [DEL] Lisp expression: (let ((field (sc-mail-field "from"))) (string-match "\"\\([^ ]+\\) \\([^ ]+\\) (EUS)" field) (match-string 1 field)) Ray
