First, thanks Gord for the assistance.

Second, the name of the add-in is Analysis ToolPak. I believed it was from
Microsoft. And it is covered in Help. But the section in Help refers to other
items, such as a Data Analysis Group, that are not in Help. Annoying but not
your problem. I have sent a nasty gram to Microsoft about it.

Third, one of my problems with Excel 2007 is that I have not found an icon
for Tools. It may be there somewhere, but I have not found it as yet. Nor
have I found how to activate it in Help. Quite annoying, but maybe it
represents my incompetence, something my wife stresses frequently.

Fourth, and most mysterious, NOW there is a Data Analysis Tab under the Data
Tab. Perhaps, I needed to reboot before it appeared because it was not there
yesterday.

Again thanks for the help.

PS The add-in is pretty slick.
