unable to schedule in cron

the follwing script is running fine , when run from the ksh shell...it runs properly i.e. waits for a file "test.flag" and sends mail accordingly.

But when I schedule it in the crontab ...it does not run at the specified time (it never runs).
I am using ksh

####shell script starts
count=1
while true; do
if test -f test.flag
then
mailx -s "File Found" s.ba@dsc.com s.ba@hcil.in </man/prd2/bat/tmp/found.txt
exit 0
fi
let count="$count + 1"
#####count=$(( $count + 1 ))
sleep 2
####wait (2)
if [ $count -gt 300 ]
then
mailx -s "File not Found" s.ba@dsc.com s.ba@hcil.in </man/prd2/bat/tmp/not_found.txt
exit 0
fi
done

####shell script ends

###ran crontab -l
20 11 * * * /sa/p/brd/tmp/mailer.sh

##### ran uname -X
System = SunOS
Node = ritba
Release = 5.8
KernelID = Generic_108528-24
Machine = sun4u
BusType = <unknown>
Serial = <unknown>
Users = <unknown>
OEM# = 0
Origin# = 1
NumCPU = 2

Please suggest, (the path of .txt files is correct)

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
	   able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
	   performed.
