Dear MOLPRO users,

I am running some calculations for MnF3 (D_{3h} geometry) in the C_{2v} 
subgroup, hoping that CASSCF state-averaging will work out for me and 
finally give me ^5E^{\prime}, ^5E^{\prime\prime} and 
5A_1^{\prime}. My input file is given below. Could anyone make some 
suggestion to me to improve this input file, since as it is it clearly 
does not work out.

Thank you

Ilias Sioutis
