    Javascript Error: Object expected

    Hi,

    I have seen emails with this particular message but they do not help me. I get this error only in IE 6 & 7. Firefox, Safari and Opera work fine.

    Can some one point out what I am doing wrong? As a result of this error, the javascript function is not getting called at all. Thanks!

    Here is the code --

    [code=html]
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
    <head>
    <title>VAP</title>
    <meta http-equiv="Content-Type" content="text/html;charset=IS O-8859-1">
    </head>
    <body>
    <script type="text/javascript">
    function process()
    {
    if (document.calcu late.case[2].checked == true)
    {
    document.calcul ate.typ[0].checked=true;
    document.calcul ate.typ[1].disabled=true;
    }
    else
    {
    document.calcul ate.typ[0].checked=false;
    obj.typ[1].checked=false;
    obj.typ[0].disabled=false ;
    obj.typ[1].disabled=false ;
    }
    }

    </script>
    <form method="post" action="calcula te.php" name="calculate ">
    <P>
    <span style="FONT-WEIGHT: bold"> Case</span>: <input onclick="proces ();" name="case" value="A" type="radio"> A
    <input onclick="proces s();" name="case" value="B" type="radio"> B
    <input onclick="proces s();" name="case" value="C" type="radio">C
    <br>
    <SPAN style="FONT-WEIGHT: bold"></SPAN></P>
    <P><SPAN style="FONT-WEIGHT: bold">Type</SPAN>:
    <INPUT type="radio" value="D" name="typ">D
    <INPUT type="radio" value="E" name="typ">E </P>
    <P>
    <br>
    <input value="Submit" type="submit">
    </P>
    </form>
    </body>
    </html>
    [/code]

      Welcome to Bytes!

      You haven't defined obj anywhere. Also, to refer to a radio button, use something like:
      Code:
      var cases = document.calculate.elements["case"];

          That is not the source of the error.

          Sorry about that. In my attempt to create a small code for people to see I made that obj error.

          Please see this. Even with the obj removed I get the expected identifier error.

              If you access the radio buttons using:
              Code:
              var cases = document.calculate.case;
var typs = document.calculate.typ;
              then use these arrays in the following way:
              Code:
              if (cases[2].checked) ...
              it should solve the problem.

              PS. please use [code] tags when posting code. Thanks!
