What were the exact commands you gave to impose the constraints and run the

The theory says that beta(1)+beta(2)+...+beta(n)=0 should hold. So
I need to estimate these equations together imposing the above
constraint. According to help the files I must be able to do this
with "sureg" and "constraint" commands. Imposing restrictions on
constants seems fine but when I impose any restriction, like the
one mentioned above, on any set of parameters other then the
constants I get the message "redundant or inconsistent constraint".
What can I be doing wrong? Is there any other way of doing this?
Thank you all beforehand for any help.
