Here is my /etc/init.d/iptables file. I could't understand it.

And when i try /etc/init.d/iptables save active it gives an error:
There is no file or directory /var/lib/iptables/active

"Savinging iptables ruleset: save "active" with
counters/etc/init.d/iptables: line 66: /var/lib/iptables/active"
