if else statement

I have a case statement inside some of the if statement, but after doing the case statement inside the if statement, the loop ends. After the case statement, it is supposed to go to the next value on the array. What's happening is the first value in the array, after passing through the if-statement then case, the script finishes instead of looping to the other values in the array.

set -A arrs a b c d

num=`expr ${#arrs[*]} - 1`

for x in `seq 0 $num`
do

var1=`some command here`
var2=`some command here`
var3=`some command here`

if [[ "$var1" == "$var2" && "$var3" == "0" ]]; then

 #do something here

elif [[ "$var1" == "$var2" && "$var3" != "0" ]]; then

 echo "\nContinue?"
 echo "[y/n]:\c"
 read yes_no

 case $yes_no in
 [yY])
   echo "You answer yes."
   echo "Some text that will go to the text file" >> some_text.txt
break
 ;;
[nN])
   echo "you answered  no"
 exit
;;
*)
  echo "\nTry again"
;;
esac

elif [[ "$var1" != "$var2" && "$var3" == "0" ]]; then

 echo "\nContinue?"
 echo "[y/n]:\c"
 read no_yes

  case $no_yes in
  [yY])
   echo "You answer yes"
   echo "Some text that will go to the text file" >> some_text.txt
  break
;;
[nN])
   echo "you answered  no"
  exit
 ;;
 *)
    echo "\nTry again"
 ;;
 esac

else
  echo "Do back flip"
exit
fi

done
