...and it will keep showing you the same errors because your input is
*not* how it is required.
you had the same kind of error before. you obviously didn't type
anything but used cut and paste, but cut and paste these days doesn't
work reliably. PDF viewers and web browsers insert "invisible" spaces
and non-ASCII characters into what you see on the screen for more
readable and better formatting. this if you just blindly cut and paste
and not check what is actually typed on a character by character basis
(thus it is best to use a real plain text editor for text input like
LAMMPS needs it), you will have the same problem over and over again.

a smart person will check this when this happened the first time and
analyse and understand previous mistakes and then learn from them.

how long do you think you can keep on doing this?
this mailing list is not a place where you can outsource your entire
thinking and problem solving. sooner or later you will have worn out
even the most generous people on the list that may still be willing to
help you at the moment because of your unparalleled ignorance,
carelessness and lack of effort to *understand* the problems you run
into. that is probably going to be the time where you run into a
problem that would actually warrant to get help from this list, but by
that time everybody will have flagged you as a person that is
primarily a nuisance and not showing any respect to the people that
did provide help and good advice.
