[jQuery] jquery validation trailing comma error

[jQuery] jquery validation trailing comma error


Hey guys,
i read about that trailing comma error in several other posts, but i
just can't fix that problem. IE7 still submits the form even if the
required fields are empty.
Here's my jquery code:
Hope you can help me. thanks in advance.
var validator = $("#adventsform").validate({
        rules: {
            anrede: {
                required: true
            },
            vorname:{
                required: true
            },
            nachname: {
                required: true
            },
            email: {
                required: true
            },
            agb: {
                required: true
            }
        },
        messages: {
            anrede: "Bitte ausfuellen",
            vorname: "Bitte ausfuellen",
            nachname: "Bitte ausfuellen",
            email: "Bitte ausfuellen",
            agb: "Die AGBs muessen akzeptiert werden"
        },
        // the errorPlacement has to take the table layout into account
        errorPlacement: function(error, element){
            if (element.is(":radio"))
                error.appendTo(element.next().next());
            else
                if (element.is(":checkbox"))
                    error.appendTo(element.next().next());
                else
                    error.appendTo(element.next());
        },
        // set this class to error-labels to indicate valid fields
        success: function(label){
            // set as text for IE
            //alert("passt");
            label.html(" ").addClass("checked");
        }
    });
