Hi gentle people

A little while back I found a great lisp routine for wiring diagrams and schedules. It puts all my entities on the snap that's set in the drawing. The problem is that it doesn't seem to do what it should to my attributes. I tried a few things, but I'm not very good at lisp (I'm more at home in VB).
Perhaps if someone here has a look that person can se what's wrong. I hope so anyway, and of course I hope that person wil be willing to share that insight. Here goes:
Code:
(defun round_number (xr n /)
