Radio Button Question

Radio Button Question


Hey all
What I am working on is a form that has a bunch of yes or no
questions. So I am using radio buttons for the yes or no. If a user
clicks the yes radio, there will be additional questions that appear
below for them to answer. If the user then clicks the no radio, the
additional questions will hide again.
I have the jQuery working just fine to show and hide the additional
questions. Where my problem is, when the user clicks either of the
radio buttons, the jQuery fires, but the radio button does not show as
being clicked. What do I need to do so that radio button shows
selected?
Here is my jQuery code:
$(document).ready(function(){
     $('[id$=_questions],[id$=_questionsLink]').hide();
    $('[id$=_y]').live('click',function(){
     var thiis = $(this).attr('id').charAt(1);
     $('#'+thiis+'_questions').show();
     $('#'+thiis+'_questionsLink').show();
     return false;
     });
    $('[id$=_n]').live('click',function(){
     var thiis = $(this).attr('id').charAt(1);
     $('[id$=_condition]').val("");
     $('[id$=_date]').find('option:first').attr
('selected','selected').parent('select');
     $('#'+thiis+'_questions').hide();
     $('#'+thiis+'_questionsLink').hide();
     return false;
     });
    $('[id$=toggle]').live('click',function(){
     var thiis = $(this).attr('id').charAt(0);
     $('#'+thiis+'_questions').toggle();
     $(this).text($(this).text() == 'hide additional questions' ? 'show
additional questions' : 'hide additional questions');
     return false;
     });
});
Thanks in advance
