not the most efficient way but it works in showing user input with case statement.

Code:
#!/bin/bash

y=1
echo -e "Choose Names as listed in the format below.\n \
1. mango\t2. tango\t3. rango\t4. exit"
read answer


while [ $y=1 ]; do
    case ${answer} in
    "[Mm][Aa][Nn][Gg][Oo]"|1)
        echo "mango"
        mode="mango"
        echo -e "Specify an Option\n1. add\t2. sub\t3. exit"
        read option
        case ${option} in
            "[Aa][Dd][Dd]"|1)
                echo "you chose add"
                ;;
            "[Ss][Uu][Bb]"|2)
                echo "you chose sub"
                ;;
            "[Ee][Xx][Ii][Tt]"|3)
                echo "goodbye"
                exit 0
                ;;
        esac
        ;;
    "[Tt][Aa][Nn][Gg][Oo]"|2)
        echo "tango"
        mode="tango"
            echo -e "Specify an Option\n1. add\t2. sub\t3. exit"
            read option
            case ${option} in
