Thank you wary match your fast reply

But the code don't working.

Here is

function waranty_last(date) {
  var waranty = document.getElementById('waranty_years').value; 
  document.getElementById('waranty_last').value = cal_waranty_last.getFormatedDate(null, date);
  document.getElementById('cal_waranty_last').style.display = 'none';
  dateFrom = new Date(date);
  var nextdate = dateFrom.setDate(dateFrom.getDate()+1);
  var waranty_end = dateFrom.setYear(parseInt(dateFrom.getYear())+waranty);
     document.getElementById('waranty_start').value = cal_waranty_last.getFormatedDate(null, nextdate); 

 document.getElementById('waranty_ending').value = cal_waranty_last.getFormatedDate(null, waranty_end);        

return true;}

 

dates 2008-07-26 nextdate => 2008-07-27 waranty_end => 1081-07-27

 

what's wrong? thanks your help

One more update is necessary
Instead of
  var waranty_end = dateFrom.setYear(parseInt(dateFrom.getYear())+waranty);
Need to be used
  var waranty_end = dateFrom.setYear(parseInt(dateFrom.getFullYear())+waranty);
