[lammps-users] Incorrect args for pair coefficients

Hello
when I run this commands:

pair_style hybrid lj/cut 20 eam
pair_coeff 12 12 eam cuu3.eam
pair_coeff 3 3 lj/cut .0191 4.6
pair_coeff 1*2 3 lj/cut .08841 3.46

I receive This error:

Incorrect args for pair coefficients .

Why???
Where is wrong?
Thanks

If I run this with the current version of LAMMPS, I get no errors.
Did you allow for 3 atoms types when you created the simulation domain?
