Hi Christoph, thanks for your response.

I could not figure out what the problem was. I solved the problem rather 
obliquely, I named each atom to be a part of different residue for the 
third molecule and in my mapping file I defined each of the mapping beads 
explicitly (=the total number of atoms). This works.

Thanks a lot again.

Cheers,
Vikram
