st: Re: problem with nlsur quaids

[minti <Mintewab.Bezabih@economics.gu.se>]

Thanks jorge for the correction.  I still get the error message(invalid
syntax 198). I have put the trace on to help me see where the problem is and
it comes right before this line

-_b[l`i']*_b[b`j']/${bp}*(lnexpmean - (${ap}))^2"

Below is  the corrected code 
thanks
