var EDate = document.form.next_date.value;

if (SDate == '' || EDate == '') {
  alert("Plesae enter both....");
  return false;
}

var endDate =new Date.parse(EDate);
var startDate =new Date.parse.Date(SDate);


if(startDate > endDate)
    {
        alert("Please ensure that the End Date is greater than or equal to the Start Date.");
        document.calldate.next_day.focus();
