JQuery Validate if CheckBox not Selected

Hello,

I'm a little bit stuck with this,

I have a form id = #BrandRate, on which I have the following -

checkbox #nextyear
Select List #nextyearreason

The #nextyearreason is required only if #nextyear is NOT checked...

So far I have (from here) --

<script>
$(".selector").validate({
   rules: {
     contact: {
       required: true,
       email: {
         depends: function(element) {
           return $("#nextyear").not(":checked")
         }
       }
     }
   }
})
</script>

Select allOpen in new window

I've not got very far I know! Also what if i need to add additional IDs that are required?

or different validation rules for different IDs?

Thanks
