    Code not working

    Some code I wrote is not working. Here it is:

    <html>
    <head>
    <title>ex 5</title>

    <script language="javas cript">

    function Average()
    {
    num_ein=window. document.Averag e.num1.value;
    num_zwei=window .document.Avera ge.num2.value;
    num_drei=window .document.Avera ge.num3.value;

    alert(num_ein+n um_zwei+num_dre i);
    }

    </script>

    </head>

    <body>

    <form name="Average">
    <input type="text" name="num1"><br >
    <input type="text" name="num2"><br >
    <input type="text" name="num3"><br >
    <input type="button" name="button1" value="Click for
    Average" onClick=Average ()>
    </form>

    </body>
    </html>

    Internet Explorer says that the button object does not support the property or
    method. Please help.

      Rename the form or rename your function.

          1. Don't give a form and a function the same name. They share name space.
          2. It's good practice to quote the value of the HTML onclick attribute.
          3. The "language" attribute of the <script> tag is deprecated.
          It's better to use: <script type="text/javascript">
          4. Once you get to the point that your function is working, you'll find
          that your alert is displaying the three string values concatinated,
          rather than converted to numbers and summed. This link should help
          you with that problem:

              In this particular instance, it's mandatory. Parentheses cannot appear in
              attribute values without quotation marks.

              Replace ".invalid" with ".uk" to reply by e-mail.
