How would I go about making it so the user ha

Answer 1

Requirement is Validation need to be either C or (A and B) is required. The thing worked for me is:

$.validator.addMethod("multipeFieldValidator", function(value) { 
    var returnVal = false; 
    if($("#Cfield").val() != '' || ($("#Afield").val() != '' && $("#Bfield").val() != '')) {
        returnVal = true;
    }
    return returnVal; 
}, 'Either C or A and B is required');


$('#Afield.form-control').change(function(){
    $(this).valid();
    $("#Bfield").valid();
    $("#Cfield").valid();

});

$('#Bfield.form-control').change(function(){
    $(this).valid();
    $("#Afield").valid();
    $("#Cfield").valid();
});

$('#Cfield.form-control').change(function(){
    $(this).valid();
    $("#Bfield").valid();
    $("#Afield").valid();
});


within rules I have 
Afield: "multipeFieldValidator",
Bfield: "multipeFieldValidator",
Cfield: "multipeFieldValidator"
