Advanced Datepicker not showing in backend

Hi,

When making a custom field i can only find the 'Simple datepicker' and not the Advanced Datepicker (is not in dropdown list). I need this because the simple datepicker is not working with this version of Joomla/hika.

I have hika business edition.

Did i miss something?

Thanx for any suggerstions.

Ow.... after a long search... I had to activate a seperate Hikashop plugin for that...
