I can't spot the problem, but I can tell you that a useful debugging
strategy is to start with a much smaller program and gradually build it
to the full model that is desired. Substantively such smaller models
may be completely unacceptable within your discipline, but don't worry
about that, it is just a step in getting the mechanics to work.
Sometimes such smaller models happen to coincide with models that are
already implemented in Stata, so you can use that as a check of whether
you start from the right point.
