[lammps-users] perhaps mistake

hello,i find there are mistake in the example of the command computer
tem/ramp. when i use this command for compute or temperature ,it says
the command can not find ,why? is it nor work?

The appended script (from bench/lj) works fine with
the compute temp/ramp command.
