And a function in lisp retur= ns the value of the last expression evaluated as the return value. Consequently, the following function will only take the last expression in = the `let' body (completing-read) to fill an element of a list for setting t= he function argument `type'. (defun myfun (type) (interactive (list =C2=A0 (let ( (rqmatch t) (initpk "mixed") (dflt "extended") (cseq '("expression" "mixed")) ) =C2=A0=C2=A0=C2=A0 (message "This is a message") =C2=A0=C2=A0=C2=A0 (completing-read "Flare_type: " cseq nil rqmatch initpk = nil dflt))))) On the other hand if I want to have multiple function arguments, I should h= ave (defun myfun (type other-arg) =C2=A0 (interactive =C2=A0=C2=A0 (let ( (rqmatch t) (initpk "mixed") (dflt "extended") =C2=A0 (cseq '("expression" "mixed")) ) =C2=A0=C2=A0=C2=A0=C2=A0 (message "This is a message") =C2=A0=C2=A0=C2=A0=C2=A0 (list =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 (completing-read "Flare_type: " cseq nil =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 rqmatch initpk nil dflt) =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 (completing-read "Other_arg: " cseq nil =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 rqmatch initpk nil dflt)))))
