How about something like this:

Code:
#!/bin/bash
menu_items=(
    "30 Minutes" "1 Hour" "6 Hours" "12 Hours" "1 Day"
    "1 Week" "1 Month" "3 Months" "1 Year" "2 Years"
    "3 Years" "Never" )
 
items_period=(
    30 60 360 720 1440
    10080 40320 151200 604800 1209600
    1814400 0 )
 
PS3="Expiration:"
select s in "${menu_items[@]}"; do
    if [[ -z "$s" ]]
    then
        echo "Option $REPLY is invalid - Please select a number from 1 to ${#menu_items[@]}"
    else
        period=${items_period[$REPLY-1]}
        echo Period selected is $period
        break
    fi
done
