Sad Optical Photon spectrum in two scintillators

Helo everyone

I have modified OpNovice example to see spectrum of optical photons in two scintillators GOS and CsI which centres are at (0,0,0) and (-4.0mm,0,0). I have wriiten following lines in "Classify New Track" method of G4StackingAction class

******************************************************************************
if(aTrack->GetDefinition() == G4OpticalPhoton::OpticalPhotonDefinition())
  { 
    if(aTrack->GetParentID()>0)
     {
     if(aTrack->GetCreatorProcess()->GetProcessName() == "Scintillation")
       {
         if(aTrack->GetVertexPoxition().x()<(-2.0*mm)
            {Counter1++;
	     G4double ge1 = (aTrack->GetKineticEnergy())/MeV;
	     OpRun->E_CsI(ge1);	 	 
  	     }

         if(aTrack->GetVertexPoxition().x()>(-2.0*mm)
            {Counter2++;
	      G4double ge2 = (aTrack->GetKineticEnergy())/MeV;
	      OpRun->E_GOS(ge2);
            } 	 	 
  	}
    }
   }
*****************************************************************************

Means if vertex position of optical photon is at x < -2.0mm then it will count in spectrum of CsI and if x> 0.0 then it will count in spectrum of GOS. Is it true?? But after simulation I get the same spectrum with same value of Counter1 and Counter2.

Can any one tell me what is going to be wrong here so that I am not geting different spectrum of the two scintillators which all optical properties are defined in G4Detector construction class differently??

Any kind of assistance will be appreciable. Thanks
