jQuery Validator: Custom message on type

I've basically got a for loop that loops through a bunch of classes does work, one for checkboxes and one for radio boxes. The fields need to be marked required when selected, or checked (which works just fine), I just need to display a custom error message for each type: checkbox and Radio box.

I've tried in the loop/method to do .validate(rules{required: 'Please select an option'}) with no luck. How can I accomplish this?

Code:

// When the DOM is ready
$(document).ready(function() {
            /* To add more boxes to hide/show, add the name of the field to the array, 
                set the box class to that name + Hide, set the class of the field to that name
                then if radio box set value="Yes" Yes must have first letter capitlized */ 
            // storing the class names of the HTML elements we want to mess with
            var hiddenClassArray = [
                        "appliedWorkedYes",
                        "workStudyYes",
                        "workHistoryYes",
                        "workWeekEndsYes",

                        ];  

            // looping over each array element, hiding them using jQuery
            for(var i = 0; i < hiddenClassArray.length; i++){
                // jQuery to append a display none. 
                $("."+hiddenClassArray[i]+"Hide").css("display","none");    
            }

            // ************ RADIO & CHECK BOXES ************

        // jQuery's Equlivant of a for each loop, a little fancier then that 
        $.each(hiddenClassArray, function(index, radio) {
