I have tried that. It was result of error in code, parenthesis
was missing. Nevertheless it is difficult to know when error
is not conclusive.

Most common unconclusive error is when I type by mistake
somewhere "n" or some letter in code and that Emacs does not
tell me why buffer cannot be evaluated.

You may close this.
