This is part of a bigger lisp. I am still not familiar how to use error handling. On occassion when I run c:t66 there is no text to be found, so it gives me an error ; error: bad argument type: lselsetp nil When I run (if txt (c:t55)(C:T66)) the lisp will crash. How can I avoid this?
(defun C:t66 () (setq txt (cdr (assoc 1 (entget (ssname (ssget "x" '((0 . "TEXT") (62 . 41))) 0))))))
(defun C:xtt () ;beginning of a bigger lisp (if txt (c:t55)(C:T66)) .......
