Zenityボタンが機能しない

だから、削除確認ボックスでキャンセルボタンが機能しない理由を理解できません...説明してもらえますか？

directory=$(zenity --entry \
    --text "Enter a path" \
    --title "Delete"\
    --ok-label "Done" )
    ret=$?

    if ((ret==0));then

        if [ -z "$directory" ];then #Check if user entered a path or not.
            directory=$(pwd)    #If not take the actual path.
        fi
        if [ -d "$directory" ];then #Check if entered path exist.
            Spath=$(zenity --file-selection --filename="$directory/" --title "File Browser")
            #Change the directory otherwise will not delete the wanted              file.           
            cd $directory
        fi
        if (($?==0));then
            #Check if the user really want to delete this file.
            zenity --question --icon-name "edit-delete" --title "Confirmation" --text "Are you sure you want to delete this file?"

            #Getting only the file name from the path
            Sfile=$(basename "$Spath")
            echo $?
            clear $?

問題はこの部分ですが、キャンセルを押すとOKボタンのパスをたどるということです。

            if (($?==0));then
                rm -f "$Sfile"  #Delete the file.
            elif (($?==1));then
                echo $?
                zenity --error --title "Info" --text "No file was deleted"
            fi      
        fi
        
    else
        #If not existing show error message.
        zenity --error --title "Error" --text "The path you entered does not exist" 
    fi
