IF statement output in bash?

When I run this script the first question it asks is "Would you like to use curl? [Y/N]:" to which my reply is often Y or y. However, when I do that the instant output I get is "Unknown!". I'm expecting to see the next question from the code which is "Great, do you want to ignore certificates [Y/N]: "

Can anyone edit my code to make it work as expected? And tell me why?

#!/bin/bash

echo "Build command"

read -r -e -p "Would you like to use curl? [Y/N]: "

curlstring="curl"

if [[ "${input,,}" == "y" ]]; then    
    read -r -e -p "Great, do you want to ignore certificates [Y/N]: " input
    if [[ "$input" == "y" ]]; then
        curlstring=$curlstring" -k"
    else
        curlstring=$curlstring" "
    fi echo "$curlstring"    
elif [[ "${input,,}" == "n" ]]; then
    echo "Bye"    
else
    echo "Unknown!"
    exit 0
fi
