Hi Chumby,
I'm totally a rookie about this argument, but i write below my code... it has some mistakes in other parts, but the datepicker seems to be ok..
I think that your code is incomplete because if you see the source code of a page with the datepicker corretly inserted by the easy wizard, you can see that there are some lines also in the header:
<head>
<link rel="stylesheet" href="http://yoursite/components/com_chronoforms/css/datepicker/datepicker_dashboard.css" type="text/css" />
<script src="http://yoursite/components/com_chronoforms/js/datepicker/datepicker.js" type="text/javascript"></script>
<script type="text/javascript">
//<![CDATA[
window.addEvent('load', function() {
new DatePicker('.cf_date_picker', {pickerClass: 'datepicker_dashboard', format: 'Y-m-d', inputOutputFormat: 'Y-m-d', allowEmpty: true});
new DatePicker('.cf_datetime_picker', {pickerClass: 'datepicker_dashboard', inputOutputFormat: 'Y-m-d H:i:s', timePicker: true, allowEmpty: true, format: 'd-m-Y H:i:s'});
new DatePicker('.cf_time_picker', {pickerClass: 'datepicker_dashboard', inputOutputFormat: 'H:i:s', timePickerOnly: true, allowEmpty: true, format: 'H:i:s'});
});
//]]>
</script>
</head>
and then the code in the body:
<div class="ccms_form_element cfdiv_datetime" id="insert_date_container_div"><label>Insert date</label><input maxlength="150" size="16" class="cf_date_picker" title="" label_over="0" hide_label="0" type="text" value="" name="date" />
<div class="clear"></div><div id="error-message-date"></div></div>
<div class="chronoform">
<a href="http://www.chronoengine.com">Powered By ChronoForms - ChronoEngine.com</a>
</div>
(and the code related to the submit button)...
I hope this will help!
Ciao!
