Shopping Cart Delivery Date (Required on) calender is blank

Hi Guru,

I have a problem when creating shopping cart by describing requirement.

Txn.BBPSC02

Shop >Describe requirement >

Fill the description,Quantity,UoM,Price,Currency,Product Category.

Now I need to select the date (system date is default) so I am clicking on the calendar to choose the date.

But the pop up window (calendar) is showing blank and I couldn't select any date.

Can any one help me how to fix the calendar . Any input appreciated.

Thanks in Advance.
