If you go to the daily sales report, then click on a day, then select a date and export that day's sales, if there are any sales for the current date, it exports them, otherwise it exports nothing. The date passed via the querystring is "undefined". The following section looks for the wrong input box, it should look for #StartDate
$("#exportReport").click(function () {
var date = $("#date").val();
var action = $(this).data('action');
window.location.href = action + "?date=" + date;
});

EDIT: If there are no sales, the ExportDailySales report says "Successfully exported" but there is no file because there are no sales. It should either show a message to that effect or not show the button to export if there are no sales for the date.
