[lammps-users] ERROR: Incorrect args for pair coefficients

hi all i have this input file. where i am trying to read the potential
of only V leaving behind Fe but i am getting an error like "ERROR:
Incorrect args for pair coefficients". It is very evident that pair
coefficient arguments are incorrect but i am not able to correct it.
can anybody help me? my EAM potential is downloaded from this site

Use the atom names, like V, instead of 1 in the pair coeff command.
