Thanks for the replies guys.

I do have SP2 installed for Office 2007. I am also able to enter in dates -
as I mentioned, I am able to set the minimum date to whatever I want. But
not the maximum date. Note that I have also used the 5-digit number approach
and I still can't set the maximum date.

By the way Jon, your website is an excellent resource of charting tips and
techniques. Whenever I need to produce a tricky graph I go to your website
first. I want to thank you for creating it.

Cheers
David
