Dear all

I have a system of five equations that I want to estimate and then test for nonlinear restrictions.
I will give an example here for two equations of the system only and a restriction that I want to test to make it simplified at this stage.

HTML Code:
nlsur(f_profit={A0}+{A1}*base+{A2}*cashf+{A3}*growth)(f_return={Beta}*(f_profit-{Ac0}-{Ac1}*base-{Ac2}*cashf-{Ac3}*growth)), ifgnls vce(robust)variables(base cashf growth f_profit f_return)

testnl [A1]+[A3]/0.3 =[Ac1]/[Ac2]*0.12
nlsur runs smoothly and provides results. I can not figure how to test the restriction using testnl or any other relevant programme. The code for testnl produces an error message.
Can any one help me to test this restriction after estimating the system>

Thanks
Mike
