How play a specific section of an AnimMontage?

I want to play an AnimMontage from SkeletalMeshComponent . its play but i cant choose to play what section no matter i do , it just play first section . ( SkeletalMeshComponent is component of a pawn ).

I will appreciate if anyone have any solution for this .

thanks .

My mistake was I using Montage_JumpToSection() before playing montage, use it after playing and its works fine.
