NBO: $CHOOSE and $DEL



 Dear netters,
     In NBO 3..0 I  generate a particular Lewis
 structure of an conjugated molecule, using
 $CHOOSE command, but I am not able to
 calculate the energy of deletion of some
 excited orbitals of this structure with $DEL.
 Is it possible?
     Thank you in advance,
                 Sergio
