Tırnak (")gözümden kaçmış ama sorun onda değil. Çıktı da normal halbuki neden çalışmıyor anlamadım.

    <script type="text/javascript">
    if (eski_ie == 1 ){document.write("<div class=\"wbrowserbox\"><b>You are using an outdated web browser</b><p>To use the site more effectively and to be able to see properly, please update your web browser software.
