Please see Please Read This First: Guidelines and Suggestions for posting LAMMPS questions about how to correctly quote input files so that they get correctly formatted by the forum software and also about which information to provide when reporting LAMMPS not working as expected.
It is very difficult to assess what is going on without being able to reproduce your calculation, and for that you need to provide all files necessary to run your input deck, unless they are part of the LAMMPS distribution.
