Поскольку имя одно и то же, я связываю обработчик событий для ввода и имени.
Я не знаю, используете ли вы jQuery или нет.
Для удобства я сделал это ниже,jQuery.
Единственное, что я сделал, это добавил обработчик событий.
$('input[name="service"]').click(function(event){
$('input[name="service"]:checked').not(this).prop('checked', false);
})
