Software :: Iptables - Unable To Log To Rsyslogd

I am using iptables and what i want to do is have is log to a specific file that i have set for it. Here is what i edited to rsyslog.conf

#kern.* /dev/console
:msg, contains, "iptables" /var/log/iptables
& ~

now as far as iptables rules here is what i am working with...

iptables -A INPUT -i eth0 -p tcp --tcp-flags ALL NONE -m limit --limit 5/m --limit-burst 7 -j LOG --log-level 4 --log-prefix "iptables"

however when i run my script i get this kind of output:

iptables v1.4.9: unknown option `--log-level'

Try `iptables -h' or 'iptables --help' for more information. when i do 'iptables -L -n' i get this kind of output..

LOG tcp -- 0.0.0.0/0 0.0.0.0/0 tcp flags:!0x17/0x02 state NEW limit: avg 5/min burst 7 LOG flags 0 level 4 prefix `iptables'

why i am getting this error unknown option '--log-level' and two why is not writing anything to /var/log/iptables when i do 'cat /var/log/iptables' i get nothing
