I assume you meant this: (defun pmchart (descr selectr nc)

You want to append the list of x's to the list containing the name, not
to the name (which is a sequence of characters, so appending to it would
make a list beginning with the numerical values of the characters of the
name):

(append (list q) (make-list p "xxxxx") (make-list (- nc 1 p) ""))
