Error while scheduling the shell script

I am getting the below error while scheduling the job.Why?

00 30 * * * /arbor/integ_fx/rahul_raj/itsr_5652_v2/it.sh /arbor/integ_fx/rahul_raj/itsr_5652_v2
"/tmp/crontabBvaWiv" 47 lines, 2412 characters
00 30 * * * /arbor/integ_fx/rahul_raj/itsr_5652_v2/it.sh  /arbor/integ_fx/rahul_raj/itsr_5652_v2
crontab: error on previous line; number out of bounds.
crontab: errors detected in input, no crontab file generated.

The syntax is <minute> <hour> <day> <month> <day of week> <command>. 30 is not a valid hour in this case

Silly me
