To echo Richard, -inteff- is just more Stata.
Thus as in a very recent thread
. viewsource inteff.ado
will show that the error arises whenever the
fourth argument is not the product of the
second and third arguments. There is a rule of
thumb decision on that.
That is, the fourth variable specified must be
an interaction term. This is explained in the
help. Judging by your variable names, this
is not true of your data.
By the way, the Statalist FAQ advises
"Before posting, consider other ways of finding information:
[...]
the authors of user-written ado-files (who usually have email
addresses, but are not always members of Statalist)"
"Say what command(s) you are using. If they are not part of
official Stata, say where they come from: the STB/SJ, SSC,
or other archives"
In this case, the program -inteff- was published in the Stata Journal.
The authors may be members of Statalist, but even so a direct
approach is often a good bet.
