comparing file files, prompt not asking for input

Question

I'm downloading files from a remote server. This part works fine but now I'm trying to compare the remote file size to the local file size.

If the two don't match then I want to prompt the user to enter yes or no

I've added the read command, but the script never pauses and asks the question. why ?

This is my test code

while IFS=',' read -r downloadfiles; do


        case "$downloadfiles" in
        AA)
            filetoget="$downloadfiles.tar.gz"
            ;;
        BB)
            filetoget="$downloadfiles.zip"
            ;;                      
        esac


        sizeoffile=`curl -sI "http://server.com/$filetoget" | awk '/Content-Length/{sub("\r","",$NF); print $NF}'`
        curl -O http://server.com/$filetoget

        localsizeoffile=`stat --print="%s" $filetoget`

        if [ "$localsizeoffile" -ne "$sizeoffile" ]; then
            echo "error..."

            read -p "Continue (y/n)?" CONT
                if [ "$CONT" = "y" ]; then
                    echo "yaaa";
                else
                    echo "booo";
                fi
            fi

done < filelist

Can anyone advise what I've done wrong. thanks

Update.. I've intentionally set it so a local file will have the wrong size so I can test.. I get the error error... but not the prompt asking if they want to continue.. any ideas

Fixed Typo

You can use this (inspired by dank's answer):

read -p "Continue (y/n)?" CONT </dev/tty
