error generated by the lisp "zero"

[Flyerr]

Hi, I'm new here. so far your explanation is very helpful, I added the _zeta command (correspondent to 'flatten) after downloading it. I added it using _appload and went bumped well. I tried to use it, I entered the height quota, I selected what I needed but when I then send in to let go of the command comes out this writing:
cannot invoke (command) from *error* without prior call to (*push-error-using-command*).
converting (command) calls to (command-s) is recommended.
At this point I don't know what to do,someone can kindly help me? Thank you!

.lsp files can be uploaded by autocad in the following ways:

-transcinating the file directly inside autocad running.
-with _appload by selecting the file and uploading it
-digitating from the command line (load "file.lsp") bearing in mind that file.lsp must be in the autocad path

to automatically load the lisp to every dwg opening you need:

-add _appload the file in the boot group.
-rename the file in acad.lsp and insert it into the search path of autocad support files
if the acad.lsp file already exists, add the content of the new lisp

to know the command of the loaded lisp:

-usually matches the file name itself
-when you charge, the indication on the command line comes out.
with an editor, for example notepad, you look for the defunc string c: , the following c: is the command. Suppose we find dead c: try, the command will be proof.

thank you, I contacted the manufacturer who kindly explained to me that depends on the fact that I work on autocad for mac. I managed to do what I needed thanks to another discussion here where I found the flatten lisp!
