Which is why you could/should construct a minimalist example that
demonstrates the problem using a data set that is available to all,
and doesn't require irrelevant detail to explain the problem you are
having.  After all other are using their "free" time to answer your
question, putting a little effort in to clarify the question in such a
manner is only being mindful of this.

Older issues of articles in the Stata Jounral are available for free
