Problem in for loop of shell scripting in solaris

Hi below is my script

for((i=0;i<=$TOTAL;i++))
do
echo "IP's created are $s1.$s2.$s3.$s4"
s4=`expr $s4 + 1`
done


where s1,2,3,4 are input varibles
below error occurs while running the script

syntax error at lin 11: '(' unexpected

Any idea

Regards
Revathi

Below is entire script

echo "Enter the start IP"
IFS="."
read s1 s2 s3 s4
echo "Enter the End IP"
IFS="."
read e1 e2 e3 e4
TOTAL=`expr $e4 - $s4`
echo "Total is $TOTAL"
if [ $e4 -gt $s4 ];then
echo "Total number of IPs are $TOTAL"
for((i=0;i<=$TOTAL;i++))
do
#/sbin/ifconfig bge0:$s4 plumb
#/sbin/ifconfig bge0:$s4 $s1.$s2.$s3.$s4
echo "Interfaces created are bge0:$s4"
echo "IP's created are $s1.$s2.$s3.$s4"
s4=`expr $s4 + 1`
done
else
echo "Smaller"
fi

Should be

Code:
#! /bin/sh


Please use CODE tags, it makes viewing the code much easier

Ya I have tried it. The same problem persisted

Code is below

#!/bin/sh
echo "Enter the start IP"
IFS="."
read s1 s2 s3 s4
echo "Enter the End IP"
IFS="."
read e1 e2 e3 e4
TOTAL=`expr $e4 - $s4`
echo "Total is $TOTAL"
if [ $e4 -gt $s4 ];then
echo "Total number of IPs are $TOTAL"
for ((i=0;i<=$TOTAL;i++))
do
#/sbin/ifconfig bge0:$s4 plumb
#/sbin/ifconfig bge0:$s4 $s1.$s2.$s3.$s4
echo "Interfaces created are bge0:$s4"
echo "IP's created are $s1.$s2.$s3.$s4"
s4=`expr $s4 + 1`
done
else
echo "Smaller"
fi



Result is

bash-3.00$ sh test.sh
Enter the start IP
1.1.1.2
Enter the End IP
1.1.1.5
Total is 3
test.sh: syntax error at line 12: `(' unexpected
