Cron did not found my script why - the ls -ltr found it

Hi experts.  I don't know how to fix or make this work.
The cron did not find my script, but my script is there and have the privileges to be executed.  


Cron Environment:
 SHELL =
 PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/java14/jre/bin:/u
sr/java14/bin
 CRONDIR=/var/spool/cron/crontabs
 ATDIR=/var/spool/cron/atjobs
 LOGNAME=oracle
 HOME=/home/oracle

Your "cron" job executed on tbsdev01 on Sun Sep 18 00:00:00 AST 2011
/home/oracle/dba/scripts/COLD_BACKUP_streams.sh TBS6DEV


produced the following output:

sh: /home/oracle/dba/scripts/COLD_BACKUP_streams.sh:  not found.
