[jQuery] jquery validation trailing comma error

[[EMAIL PROTECTED]]

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
