[jQuery] [validate] need help with addMethod


Trying to add a new validation method to check a yes/no set of radio
buttons:
My method:
    $.validator.addMethod("checkyesno", function(value) {
     if (value == 'Yes') {
     return true;
     } else {
     return false;
     }
},
"You must read and agree to the terms and conditions before
proceeding.");
My rules:
    rules: {
        terms: {required: true, checkyesno: true}
        },
But so far have not been able to make this work... What am I doing
wrong??
Thanks!
Jim
