iptables problem script

Hello everybody!
I am having a problem with a iptables script, i hope someone can help me understand, here is one of the problem:
/sbin/iptables -A OUTPUT -o $EXTINT -p UDP --sport $LOCALPORTS -m state --state NEW,ESTABLISHED --dport 53 -j ACCEPT

it returs this:
iptables v1.2.6a: invalid TCP port/service `--dport' specified
Try `iptables -h' or 'iptables --help' for more information.

I have used this script and modifyed it, but her is the orginal:
http://home.swbell.net/berzerke/ipta...llv0.92.script

thanks

you cant use --dport untill you have specified a protocol...
UDP is not a valid protocol, however udp is.

(case sencitive)

I found the problem... an variabel had lost it's value...
