How can this be done? Sure, but me personally, I prefer using `cond' but would not mix it with `if' in the same time: Instead of: (defun txcomplt-light (featr) "DOCSTRING." (cond ((eq 'company featr) (if (equal 2 (aref recorder 0)) (message "Light | Green") (message "Light | Amber"))) ((eq 'corfu featr) (if (equal 2 (aref recorder 1)) (message "Light | Green") (message "Light | Amber")))) ) (defun txcomplt-light (featr) "DOCSTRING." (cond ((and (eq 'company featr) (equal 2 (aref recorder 0))) (message "Light | Green")) ((and (eq 'corfu featr) (equal 2 (aref recorder 1))) (message "Light | Amber")))) However, I did not maybe make your logic right. I hope you see that `if' is not necessary. To make function return anything, just make the value that you wish returned the last one: (defun txcomplt-light (featr) "DOCSTRING." (cond ((and (eq 'company featr) (equal 2 (aref recorder 0))) (message "Light | Green") "Green") ;; this is what is returned ((and (eq 'corfu featr) (equal 2 (aref recorder 1))) (message "Light | Amber") "Amber"))) ;; this is what is returned -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
