could you show us the crontab -l and the permission to the path you'r script lies in. for instance /etc/etc does not have +x then your script might not be able to be launched.
The file:
00 10 * * * /usr/local/bin/shellscripthere
The shellscript has rw and nor x permissions...
in /var/cron/tabs
What does it need to ahve?
Thanks.
