[jQuery] (validate) Validating multiple drop down boxes


Hi All,
I need to check that a user's birthday has been filled out completely,
using drop down menus. I can validate each of the menus individually
(see code below), but what i really want to do is make one check that
all three are selected so that I don't have 3 extra error labels...
Any suggestions?
     $(document).ready(function(){
            $("#form1").validate({
                rules: {
                    MOB: "required"    ,
                    DOB: "required",
                    YOB: "required"
                },
                messages: {
                    MOB: "Need a month",
                    DOB: "Need a Day",
                    YOB: "Need a year",
                }
            )};
        )};
<html>
                 <label for="MOB" id="lblDOB">Date of Birth</label><br />
                    <select id="MOB" name="MOB">
                     <option value="" selected="selected">Month</option>
                     <option value="2">January</option>
                 </select>
                 <select id="DOB" name="DOB">
                     <option value="" selected="selected">Day</option>
                     <option value="2">02</option>
                 </select>
                 <select id="YOB" name="YOB">
                     <option value="" selected="selected">Year</option>
                     <option value="1906">1906</option>
                     <option value="1907">etc. etc.</option>
                 </select>
</html>
