  <script language="javascript" type="text/javascript">
  
  // Function to validate dates before processing
  function dateValidation()
  
  {
  var obj = document.getElementById("departdate");
  
  var day = obj.value.split("/")[0];
  var month = obj.value.split("/")[1];
  
  var year = obj.value.split("/")[2];
  if ((day<1 || day >31) || (month<1&&month>12)&&(year.length != 4))
  
  {
  alert("Invalid Format");return false;
  
  }
  
  else
  
  {
  var dt = new Date(year, month-1, day);
  
  var today = new Date();
  if((dt.getDate() != day) || (dt.getMonth() != month-1) || (dt.getFullYear()!=year) || (dt>today))
