Please don't SHOUT
"no good" is not very informative; tell us exactly what you typed,
what Stata told you in return and why you think this is a problem. The
key word is _exactly_.
please give complete references, author + title is not a complete reference.
If your mentor suggested that you ask the authors, than why have you
not done so?
