Could anyone help with a cronjob problem?

Hello

Could anyone help with a cronjob problem.

This is the cronjob -
3,10,15 * * * * /bin/bash /home/admin-user/hl/bash-mysql.sh >/dev/null 2>&1

when I run this from the command line -
/bin/bash /home/admin-user/hl/bash-mysql.sh >/dev/null 2>&1

It all works, so I'm guessing it's something wrong with the crontab it's self, but I'm at loss with what's wrong.

Below is the status, which show something is running -

Jul 21 17:55:01 ML CRON[42571]: pam_unix(cron:session): session opened for user root(uid=0) by (uid=0)

Any help would be appreciated.

Thanks
