Hi I new to shell scripting and need help to continue my work.here is the code I have so far.

#!/bin/sh
touch fileuseranswer
echo "**********WELCOME TO GROUCHO MARX UNIVERSITY**********"

echo Username:
read i
echo Password:
read j
Username="${i}:${j}"

if ( ! grep -q $Username /$HOME/PhaseTest/userinfo )
then
echo "Wrong Login/Passwd"
exit 2
fi

echo
echo -e " \c"
date
QFILE=./questions
# max questions
max=$(sed 's/^[1-8][0-8]*\. /#&/' ${QFILE} | nawk -v FS="\n" -v RS="#" 'END {print NR}')

question(){
clear
sed 's/^[1-8][0-8]*\. /#&/' ${QFILE} | awk -v FS="\n" -v RS="#" -v VAR="$1" '(NR==VAR){print$0}' | tee q.tmp
#sed -n '/^'`echo "$1"`'\./,/^d) /p' ${QFILE}

while :
do
echo "Enter your choice :"
read b
if ( ! grep "$b"')' q.tmp >/dev/null ) ; then
echo "Invalid choice"
rm q.tmp
RC=1 ; break
else
rm q.tmp
grep -v ^$1 fileuseranswer >fileuseranswer.tmp
echo "$1 $a" >>fileuseranswer.tmp
cat fileuseranswer.tmp >fileuseranswer
rm fileuseranswer.tmp
RC=0 ; break
fi
done
return $RC
}

while :
do
echo -e "Enter question number, N for next question, P for previous question or Q for done"
read a
case $a in
[1-8]*) [[ $a -gt $max ]] && c=$max || c=$a ; question "$c" ;;
n|N) [[ $c -lt $max ]] && let c+=1 || let c=1 ; question "$c" ;;
p|P) [[ $c -ge 1 ]] && let c-=1 || let c=$max ; question "$c" ;;
q|Q) exit 0 ;;
*) echo "Wrong choice , try again" ;;
esac
done

answers(){
echo -e "\c" > fileuseranswer
QNUM=0
TOTAL=0
while [ $QNUM -lt ${#questions[@]} ]
do
echo "\"${FILEUSERANSWER[$QNUM]}\" " >> fileuseranswer
[ "${CORRECT[$QNUM]}" = "${FILEUSERANSWER[$QNUM]}" ] && let SCORE=SCORE+1
let QNUM=QNUM+1
done
echo "You got $TOTAL questions correct out of ${#questions[@]}"
}

I want to be able to output and confirm my answers to the file fileansweruser where i already have my answers.Please help to troubleshoot these lines of code.

Thanks
