ERROR: Incorrect args for pair coefficients".

hi all I have this input file. where I am trying to read the potential
of NiTi.eam.fs but i am getting an error like "ERROR:
Incorrect args for pair coefficients".
can anybody help me? my EAM potential is downloaded from this site

http://atomistics.osu.edu/eam-potential-generator/potential.php

you define only 1 type here

lattice bcc 3.051
region NiTi block 0 140 0 100 0 140 units box
create_atoms 1 region NiTi units box
timestep 0.002
pair_style eam/fs
pair_coeff * * NiTi.eam.fs Ni Ti

you require 2 types here, one more than you asked for earlier
