                var AnswersString = "<%#Eval("Answer") %>";

                var NumberOfAnswers = AnswersString.split(',').length;

                $(":checkbox").click( function()
                {
                    if(CheckedTotal() > NumberOfAnswers)
                        $(this).removeAttr('checked');
                });

                function CheckedTotal()
                {
                    return $(":checked").length;
                }
