Hello Julissa,
That screenshot is perfect. I think I have found the problem.
It looks you have \ back slashes \ in your command. Take these out, the try running the command again.

P.S. I should explain that back slashes separate a command between multiple lines. Like this
command --i file --o files --note "This works"
command --i file \
--o files \
--note "This works, and it's on three lines"
command --i file \ --o files \ --note "this does NOT work"
