2.     $(document).ready(function () {
3.         $("input.commentBox").click(function () {
4.             if ($(this).closest('div.editor-field2').children('input:checked').val() == "True") {
5.                 $(this).closest('div.formQuestion').children('div.hidden').slideDown(800);
6.             } else {
7.                 $(this).closest('div.formQuestion').children('div.hidden').slideUp("fast");
8.             }           
9.         });
10.     });

It works great if the input item is a radio button, but if I change it to a checkbox with the same class name .commentBox it no longer works.  Can someone esplain to me way?

Thank you for reading my post.
