Defining a date for the datepicker?

Defining a date for the datepicker?


Hi guys,
I currently have this code to display and configure a datepicker:
$("#datepicker").datepicker({changeMonth: true, changeYear: true,
minDate: 0, dateFormat: 'dd/mm/yy'});
It works fine, but for some reason I can't set a default value for the
picker... manually defining the value="" in the input displays it, but
the picker doesn't recognise it, so that's not really an option
unfortunately.
I've also tried the defaultDate function, but had no joy with that
either.
Any advice please?! I'm at a loss with this to be honest.
Cheers
