The /etc/crontab file is the _system_ cron file, it needs a user defined
in the sixth field for the command to run as.  Look at this line from
your original post:

    # m h dom mon dow user  command

Notice that the sixth field is for the user and the command to be run is
the seventh.  For more info check 'man 5 crontab'

Really though, this is the wrong place to put _personal_ cron entries.
You should be putting them in your own cron which you can edit with the
command 'crontab -e'.  The '-e' option launches your editor defined in
the EDITOR or VISUAL environment variables (vi by default).

Check 'man crontab' for more.
