Question

On the form I need to provide the validation where the validation depends on the value of two fields, but I can not seem to get it to work.

$.validator.addMethod("validateTask",function (value, element, params) {
        if (($("#ID").val() == 1) && ($("#IDName").val() == 0)) {

                return  "required";


            }
    }, 'Enter an individual.');

and the call is

Name:{
        validateTask: true
    }

From the plugin docs, it appears all you need is a required dependency callback

$(selector).validate({    
    rules:{
       Name:{
           required: function(element){
            return $("#ID").val() == 1 && $("#IDName").val() == 0;
       }
    },
    messages:{
        Name:{ required: 'Enter an individual.'}
    }
})
