Regarding pair_style hybrid

Dear lammps users,

I am working in a problem of CNT formation from cluster of Fe atoms and carbon atoms.I had given the potentials as below,

pair_style hybrid airebo 3 eam/fs lj/cut 10
pair_coeff * * airebo /home/labuser/lammps-5Dec10/potentials/CH.airebo C C
pair_coeff * * eam/fs /home/labuser/lammps-5Dec10/potentials/Fe-C_Hepburn_Ackland.eam.fs Fe C
pair_coeff 2 2 lj/cut 0.105 3.85 10

But the error is coming as Pair hybrid sub-style is not used.Please help me on this problem.

The eam/fs coeffs are wiping out the airebo ones, since both are
applied to all atom types. So it then thinks airebo is not used.
Maybe you want hybrid/overlay? Although I can't imagine computing
airebo and eam/fs together is a good model for any material.
