  <h3>Demonstration # 1</h3>

    This demonstration caters for Netscape 4, but showing the date value in a text box. The trigger is a button, and the data container is the text box.<br><br>

    <blockquote>
    <form name='mainform' method='post'>

      <input type=text name='datevalue' size=10 maxlength=10 value='25/07/2003'>

      <script language='javascript'>
      <!--

        if (!document.layers) {

          document.write("<input type=button onclick='showCalendar(this, mainform.datevalue, \"dd/mm/yyyy\",null,0,15,150)' value='select' style='font-size:11px'>")

        }

      //-->
      </script>

    </form>
    </blockquote>

  <h3>Demonstration # 2</h3>

    The following demonstration uses a button as both a trigger and data container. Selected language is german.<br />
    <font color='#a0a0a0'>(You will not see anything below if you are using Netscape Navigator 4)</font>
    <blockquote>

      <input style='font-size:11px' type=button value="28.07.2003" onclick='showCalendar(this, this, "dd.mm.yyyy","de",1)'>
