Question port forwarding --state (command not found?)

So I added the following to my iptables script:

#echo "Enabling PORTFW Redirection on the external LAN.."
#   This will forward ALL port 80 traffic from the external IP address
#   to port 80 on the machine
#   Be SURE that when you add these new rules to your rc.firewall-*, you
#   add them before a direct or implict DROP or REJECT.

# NOTE:  If you are using the basic rc.firewall-iptables ruleset, you
#        will need to enable the following EXTIP option.  Users of the
#        rc.firewall-iptables-stronger ruleset already have this defined.
#  *PLEASE* look over the rc.firewall-iptables-stronger ruleset for more 
#            specific issues regarding dynamic vs. static IP addresses
# Determine the external IP automatically:
# ----------------------------------------
#  The following line will determine your external IP address.  This
#  line is somewhat complex and confusing but it will also work for
#  all NON-English Linux distributions:
# DISABLED by default -- to enable, REMOVE both the "#" characters below
#/$EXTIF/'{next}//{split($0,a,":");split(a[2],a," ");print a[1];exit}'`"

# Allow forwarding of new and existing port 80 connections from the external
# interface.  This rule is required as our default FORWARD policy is DENY.
$IPTABLES -A FORWARD -i $EXTIF -o $INTIF -p tcp --dport 80 -m state \

#Enable PORTFW of this port 80 traffic from the external interface
$IPTABLES -A PREROUTING -t nat -p tcp -d $EXTIP --dport 80 -m state \ 

and i get the following error:

   - Loading OUTPUT rulesets
./rc.firewall-iptables-stronger: line 621: o: command not found
Bad argument ` '
Try `iptables -h' or 'iptables --help' for more information.
./rc.firewall-iptables-stronger: line 663: --state: command not found
     - FWD: Allow all connections OUT and only existing/related IN
i copied and pasted from the site:

So why would the --state command be not found if the statement right above went just fine and its identical?

The line 663 is the one with the *** at the begining btw.

Appreciate any help

this is on centos OS btw.

Could it be because you've configured earlier line 621 wrong and the ipt_state module isn't loaded?:
./rc.firewall-iptables-stronger: line 621: o: command not found
As root: "grep -q ^ipt_state /proc/modules || modprobe ipt_state".

good eye, there was a line with just a "o" at the beginning, insteado f a "echo -e"

That fixed it.

i cant believe i didnt see the line 621 error.
