Variables are defined above this section, of course

And, again, the functions are:

                      <!-- jQuery Script to hide/show radio buttons -->
                      <script type="text/JavaScript" Language = "JavaScript">
                       
                        $("#AHYSChk<<ch>>").click(function()
                           {
	                         if $('#AHYSChk<<ch>>').is(':checked')

	                            { $('#YSElig<<ch>>').show(); 
	                            }	
	                         else
	                            { $('#YSElig<<ch>>').hide(); 
	                            }
                           }
                         

>>>Probably the fact the :ischecked should be in quotes:

if ($'#AHYSChk01').is(':checked'))

>>Apparently, it's not recognizing the 'onclick' routine.

>So what's the html for the element with the 'AHYSChk01' Id ?
