the error message *very* clearly explains what the problem is.

as steve already has already told you, the resolution for this is very
straightforward.
i also suggest you do a more detailed study of the documentation of
the variable command. it will be worth it.

i use lammps ( version 13 dec 2016, platform ubuntu 16.04)

please do yourself a favor and upgrade to a newer version (like 16
March 2018), if you can. you will specifically gain better error
reporting on variable uses with this version (and have many bugs
fixed).

axel.
