Transporting EM Particles in multiple regions.

Dear FLUKA users,

I am wondering if there is a way to transport EM particles in multiple regions made up of different elements. I have tried to transport EM particles in a volume made up of two separate regions. One region is aluminum and the other is tungsten. I have created a pemf file which has both of those elements in it but for some reason the program only regonizes the second element defined in the file. The program stops with the message:
         Composition of Emf medium # 1, name: ALUMINUM, density: 2.70E+00 g/cm**3
            Chem. sym. : AL, Z = 13., A = 26.982, PZ = 1.00000E+00 , RHOZ = 2.69890E+00
         Rayleigh data available for medium 1 but option not requested.

         End Of File on unit 12

         Program stopped in Emfret because the
         following names were not recognized:

                                                'TUNGSTEN '
I was wondering if there is a way to get the program to recognize both elements in separate regions. One other quick question which I have. Is it okay to define two separate RESNUCLEi cards to score residual nuclei production for two separate regions? Any assistance is greatly appreciated.
