Does anybody know what is wrong here. I am running centOS

Code:

the anticrash gives me this.

#!/bin/sh

while true
do
  rm banme.tmp
  :> banme.txt
  /usr/sbin/tcpdump -p -c 100 -n -i eth0 "dst host 66.197.12 6.19 and udp port 7777" >banme.tmp 
  grep "length 0" banme.tmp | cut -f 3 -d " " | cut -f 1-4 -d "." >> banme.txt
  if [ `grep -c . banme.txt` -gt 0 ]
  then
    ip=`head -1 banme.txt`
    if [ `grep -c ${ip} /etc/sysconfig/iptables` -eq 0 ]
    then
      dat=`date`
      echo "${dat} adding ${ip} to iptables" >> banme.log
      /sbin/iptables -A INPUT -s ${ip} -j DROP      
      /sbin/iptables-save > /etc/sysconfig/iptables
    else
      echo "${ip} is already in iptables" 
    fi   //LINE 20<<
  fi
  sleep 0
done

[root@inerdtech control]# sh ./anticrash.sh

./anticrash.sh: line 20: syntax error near unexpected token `fi'

       ip6tables-save [-M modprobe] [-c] [-t table]

DESCRIPTION

       iptables-save  and ip6tables-save are used to dump the contents of IP or IPv6 Table in easily parseable format to STDOUT. Use I/O-redirect-
       ion provided by your shell to write to a file.

       -M, --modprobe modprobe_program

	      include the current values of all packet and byte counters in the output

       -t, --table tablename
