From: Fred Smith on
Your most likely problem is your cell doesn't have a date in it, it has
text. You need to convert the text to a date.

To confirm this, simply enter 12/02/10 in your cell. See if that solves your
problem. If it does, then you will need to convert your other cells to
dates.

Regards,
Fred
