st: gllamm syntax

   I am trying to run gllamm for a 3-level nested model (patients nested within 
doctors within clinics). I have 4 patient level covariates (gender, age, race 
and education) & 1 doctor level covariate (specialty). I am not sure about the 
correct syntax for running a random coefficient model. Can anyone take a look 
and point me to the right syntax. Here's what I used which is wrong.


gen byte one = 1
eq cons : one
eq gen  : new_gen
eq race : new_race
eq educ : edulvl
eq age  : age1

gllamm zeta1 new_gen age1 edulvl new_race specialty, i(docid clinicid) nrf(1 8)  
eqs(cons cons new_gen cons new_race cons edulvl cons age1) 

I get the following error message: 

equation new_gen not found


If I want to enter a random effect (intercept and slope) for doctor specialty, 
what will be the modification. Also is there a way to make it run faster using 
the `nip' command?
