Invalid mass value

Hi

Greetings .

I made TIP4P water data file with using of Moltemplate .
but now I have an error " Invalid mass value (…/atom.cpp:1267) "
Can you please let me know what the problem is ?
I know this error is Self-explanatory however I couldn’t find the reason

This is a part of my data file :

LAMMPS Description

256 atoms
128 bonds
64 angles
0 dihedrals
0 impropers

3 atom types
1 bond types
1 angle types

0.0 20.0 xlo xhi
0.0 20.0 ylo yhi
0.0 20.0 zlo zhi

Masses

1 15.999
2 1.008
3 0.0

Atoms

I also attached data file with this Email.

Here you are. As the error message says, a mass of zero is not allowed.
