Hi Bob,
Happy with the Date_Range_Picker, using your script (and FAQ)

But how do I get the totals days from this script?

<?php
JHTML::_('behavior.mootools');
$picker_array = array(
  'Picker.js',
  'Picker.Attach.js',
  'Picker.Date.js',
  'Picker.Date.Range.js',
  'Locale.nl-NL.DatePicker.js'
);
$doc =& JFactory::getDocument();
foreach ( $picker_array as $v ) {
  $doc->addScript(JURI::base().'components/com_chronoforms/js/datepicker_moo/'.$v);
}
$doc->addStyleSheet(JURI::base().'components/com_chronoforms/js/datepicker_moo/datepicker.css');
$doc->addStyleDeclaration("
.datepicker tr, .datepicker td {
  border:none;
}
");
?>
var dp, date_range;
window.addEvent('domready', function() {
  date_range = $('date_range');
  dp = new Picker.Date.Range(date_range, {
    pickerClass: 'datepicker',
    columns: 2,
    minDate: new Date()
  });
});

Any thoughts on this?

Hi SPABO,

You can add a function to the Picker's OnSelect event that will do a calculation:

  dp = new Picker.Date.Range(date_range, {
    pickerClass: 'datepicker',
    columns: 2,
    minDate: new Date(),
    onSelect: function(date) {
      //some calculate function here
    }    
  });

The datepicker documents are here

Beat me ....sorry, but it does not ring a bell or whatever......

Bob,
Struggling what you mean by

You can add a function to the Picker's OnSelect event

What/where can we find a Picker's OnSelect event?

Next to this:
I cannot find the code for the startdate and enddate, so..how should i be able to calculate??

Hi SPABO,

the code would go where I put //some calculate function here in my earlier post.

I'm not sure how to get the date values without going back to the DatePicker documents and building an example.
