Date Picker not working

Hi

I have configured a date picker field in my contact 7 form but it is not working. Was working on other site with wordpress 4.01 – is there a compatibility issue with the date-picker and version 4.1.1?

My url is http://debbiekellyphotography.com/contact-us/

Thanks Shane
