mutipe rules in form validation

Hi
I'm using jquery.validate.js . I have the following code in the head
  <script type="text/javascript">
      $.metadata.setType("attr", "validate");  
 
      $(document).ready(function(){
        $("#subscriptionForm").validate({
          rules: {
            cemail: "required email",
            cemail_again: {
              equalTo: "#cemail" ,
                    
                   cpassword: "required password",
                  cpassword_again: {
              equalTo: "#cpassword"
                        }
                  }
          }
        });
      });
  </script>

If I place more than one rule in this code, only one part works, (i,e., the form will check that the two email fields match, or that the 2 passwords match, not both sets. So, if I omit the password code, the email works fine, and visa versa. Can anyone help? Here is a link to the form, http://www.districtadministration.com/layouts/subscriptions/print_subscribe.html

Thank you in advance,
Sharon
