NUMBER OF OCCUPIED ORBITALS NOT CONSISTENT WITH NUMBER OF ELECTRONS FOR CCSD

[Elizabeth Aubin]

Hi, 

I am trying to run a molpro calculation with this input information but I keep getting the error: 

 NUMBER OF OCCUPIED ORBITALS NOT CONSISTENT WITH NUMBER OF ELECTRONS FOR CCSD. Can anyone help?

geometry={H;
           C1,H,r1;
           C2,C1,r2,H,theta1;
   C3,C2,r3,C1,theta2,H,beta;
           O,C3,r4,C2,theta3,C1,alpha}                                           !z-matrix geometry input
