Jquery validation error placement (radio buttons)

I'm trying to use the Jquery validation plugin to validate my form. I have error messages appearing to the right of most of my input elements, but radio buttons are giving me nothing but trouble.

If I don't give a width for the div.group class, the error message appears on the outside of the full page (since I assume the div width is 100% of the page?) Not doing anything causes the error message to appear after the first radio button instead of the 2nd. I can't hardcode a width, since i want to use it on radio groups of several widths. How can I just make it appear at the right edge of wherever the radio buttons in the Radio buttons ends?

Thanks!

var validator = $("#myForm").validate({
        errorElement: "div",
        wrapper: "div",  // a wrapper around the error message
        errorPlacement: function(error, element) {

            if (element.parent().hasClass('group')){
                element = element.parent();
            }


            offset = element.offset();
            error.insertBefore(element)
            error.addClass('message');  // add a class to the wrapper
            error.css('position', 'absolute');
            error.css('left', offset.left + element.outerWidth());
            error.css('top', offset.top);
    }
});

And then

<p>
    <div class="group">
        <label>Gender</label>
        Male: <input id="gender_male" type="radio" name="gender" class="required" value="Male" />
        Female: <input id="gender_female" type="radio" name="gender" class="required" value="Female"  />
    </div>

Maybe just a way to have the error message appear after the last radio button in the group? If I could get a handle to the last element, I could change the offset accordingly.

EDIT: Aha, I just used div.group{display:inline-block;}.
