I just found this Validity plugin:

http://validity.thatscaptaintoyou.com/

which states it does conditional validation but I cant figure out what the syntax is to get it to work with a radio button?

Can someone tell me if it does do conditional validation with a radio button and if so please give me an example on the net to follow.

Also If validity does not do conditional validation with radio buttons can you please point me in the right direction?

Thanks!

Depends on what kind of conditional validation you need to do on the radios.

where at least one radio button is required and one out of several check boxes are required.

I cant find a definite javascript plugin that will validate based on this criteria.

I put up a simple example using the documentation. For radio buttons make one of them default selected so that will avoid the validation. If not follow the same code, just replace the checkbox with radio. They will work the same way.

<html>
    <head>
        <title>Conditional</title>
        <link rel="Stylesheet" type="text/css" href="jquery.validity.css" />
        <script type="text/javascript" src="jquery.js"></script>
        <script type="text/javascript" src="jquery.validity.js"></script>
        <script type="text/javascript">
            $(function() { 
                $("form").validity(function() 
				{ 
					var fields = $("input[name='maillist']").serializeArray();
					var isNotChecked = true;
					
					if (fields.length == 0) 
					{
						isNotChecked = false;
					}
					
                   $("#choice")
						.assert(
							(isNotChecked), 
							"Please select at least one choice"
						);

                });
            });
        </script>
    </head>
    <body>
        <form action="conditional.htm" method="get">	
			<div id="choice">
			</div>
			<div>
			Choice1<input type="checkbox" id="maillist1" name="maillist" /><br>
			Choice2<input type="checkbox" id="maillist2" name="maillist" /><br>
			Choice3<input type="checkbox" id="maillist3" name="maillist" /><br>
			Choice4<input type="checkbox" id="maillist4" name="maillist" /><br>
			</div>
            <input type="submit" value="Submit" />
        </form>
    </body>
</html>

your example works when validating only the radio button,  but I am having trouble incorporating this with multiple conditional validations which is the ultimate goal.    With the script below I see that the validation is running on submit (alert messages appear on the screen) but then the form continues the submit operation without stopping. Please advise where my syntax has gone wrong.
$(function() 
	{ 
        $("form").validity(function() 
		 { 
			
			 if ($("#_2B_Industrial_Operations").attr("checked")) 
				{
					var fields = $("input[name='_2B_IO']").serializeArray();
					var isNotChecked = true;
							
							if (fields.length == 0) 
							{
								isNotChecked = false;
							}
							
						  $("#choice")
								.assert(
									(isNotChecked), 
									"Please make a selection");
							
					if ($("#_2B_IO_3").attr("checked")) 
						{
			
						$("#_2B_IO_Other_field")
						.require()          
						.maxLength(50);
						
						}			
				}
				
			if ($("#_2C_Ballast_Water_Treatment").attr("checked")) 
						{
							$("#_2C_BWT_Derivitives")
								.require("Value is required.")
								.maxlength(50);
						}
        });
    });
