	if ($('#shipping_controls').is(':visible')) {
		if ($('#shipping_to_show').is(':checked')) {
			$('#shipping_fields').hide();
		};
		$('#shipping_to_show').on('change', function () {
			$('#shipping_fields').toggle();
		});

	if ($('#billing_controls').is(':visible')) {
		if ($('#billing_to_show').is(':checked')) {
