Masscan & Nmap script - linux

Question

I'm currently studying pen-testing and in the exercise book "Mastering kali linux for advanced penetration testing-second edition" and the script they give for Masscan & Nmap(combined) is this:
#!/bin/bash
function helptext {
echo "enter the massnmap with the file input with list of IP address ranges"
}
if [ "$#" -ne 1 ]; then
echo "Sorry cannot understand the command"
helptext>&2
exit 1
elif [ ! -s $1 ]; then
echo "ooops it is empty"
helptext>&2
exit 1
fi
if [ "$(id -u)" != "0" ]; then
echo "I assunme you are running as root"
helptext>&2
exit 1
fi
for range in $(cat $1); do
store=$(echo $range | sed -e 's/\//_g')
echo "I am trying to create a store to dump now hangon"
mkdir -p pwd/$store;
iptables -A INPUT -p tcp --dport 60000 -j DROP;
echo -e "\n alright lets fire masscan ****"
masscan --open --banners --source-port 60000 -p0-65535 --max-rate 15000 -oBpwd/$store/masscan.bin $range; masscan --read$
if [ ! -s ./results/$store/masscan-output.txt ]; then
echo "Thanks for wasting time"
else
awk'/open/ {print $4, $3, $2, $1}' ./results/$store/masscan-output.txt | awk'
/.+/{
if (! ($1 in Val)) { Key[++i] = $1; }
Val[$1] = Val[$1] $2 ",";
END{
for (j = 1; j <= i; j++) { printf("%s:%s\n%s", Key[j], Val[Key[j]], (j == i) ? "" : "\n"); }
}'>}./results/$store/hostsalive.csv
for ips found in $(cat ./results/$store/hostsalive.csv); do
IP=$(echo $TARGET | awk -F: '{print $1}');
PORT=$(echo $TARGET | awk -F: '{print$2}' | sed's/,$//');
FILENAME=$(echo $IP | awk'{print "nmap_"$1}');
nmap -vv -sV --version-intensity 5 -sT -O --max-rate 5000 -Pn -T3 -p $PORT -oA ./results/$store/$FILENAME $IP;
done
fi
done
I wrote it out by hand just to make sure it was done correctly and when i run after doing chmod +x (filename.sh) it i get:
(running ./filename.sh) i get "Sorry cannot understand the command
enter the massnmap with the file input with list of IP address ranges"
(running ./filename.sh ipran.txt) i get "./anyname.sh: line 37: syntax error near unexpected token found'
./anyname.sh: line 37:for ips found in $(cat ./results/$store/hostsalive.csv); do'"
i am meant to get "I am trying to create a store to dump now hangon" "alright lets fire masscan ****"
i have tried using different ips(in my ipran.txt file)
any help would be greatly appreciated
