Crontab error mails

[Johan Paul]

Hi all!

What did I do wrong here; I edited /etc/crontab by adding two lines for 
execution and I think I even added then syntactically correct. I ran 
(just like Handbook told to do) crontab /etc/crontab. Now I get emails 
that say:

Subject: Cron <root at silakka> root	/usr/libexec/atrun

root: not found

root is the user that should run the lines. Here is a line from crontab:

# make full backup weekly
00     4       *       *       7       root    /usr/local/sbin/full_backup


I commented out the lines that I added but still I get lines like that...

Any help? Thanks!
