[molpro-user] Li+ MP2 problem

[AYORINDE HASSAN]

Hi all,
I am a new molpro user. I was trying to run an mp2 energy calculation of Li cation(Li+) as a test, but I always encounter an error which is absent when i run hartree fock or dft. The error is as follows:
 GLOBAL ERROR fehler on processor   2                                         

 GLOBAL ERROR fehler on processor   0

 The number of valence orbitals is .le. 0.
 One possible cause of this is that there are no orbitals available, ie you might have forgotten
 to do a Hartree-Fock calculation. Another possiblity is that the number of electrons is .le. half
 the number of uncorrelated core orbitals.

Can someone kindly tell me why I am encountering this error at the MP2 level? I am missing something in my input file?
