Zenity 버튼이 작동하지 않습니다

그래서 삭제 확인 상자에서 취소 버튼이 작동하지 않는 이유를 이해할 수 없습니다... 설명해 주실 수 있나요?

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 $?

문제는 이 부분인데, 취소를 누르면 OK 버튼 경로를 따라간다는 점입니다.

            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
