CRON won't run system commands (even as root)

hi. I am trying to figure out why CRON *will* execute this script, but it won't actually do what it's supposed to do.

here's a copy of a simple script (/usr/local/bin/shelltest):

groupadd mytest22

Here's my crontab file:
[root@internetsubmit internetsubmit]# crontab -l
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.24499 installed on Tue Mar 19 01:14:24 2002)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
13 * * * * /usr/local/bin/shelltest

when I install as root into CRON, it will not create the group "mytest22" but if i run the script from the command line, it works fine. I've tried this on two systems (Redhat & Mandrake) and nothing. There must be something about CRON that I am overlooking...perhaps it has a safety feature?? Anyone know how to fix it so I can create users/groups into the system using CRON?

you need to use a full path to groupadd
Also see the crontab user's mail, 'cause cron sends a mail if it fails.
