Dear Molpro users & Developers

I am getting a very strange error in SAMC directive


My input file is
***,MOLPRO.input generated by molpro_input.py Version 1.0
memory,125000,k



print,orbitals,civectors;

dkroll=1
dkho=2
basis=6-31G**

}

};

{forces;SAMC,5001.2};

I am getting this error----- "
" Illegal directive SAMC for program FORCES  "
In output it uses numerical gradient. I think that, cpmcscf  (SA-MCSCF )
uses analytic gradient.

Kindly help me.

Thanks in advance
