You can then clear the contents from the first two cells to keep your
worksheet clean. If you really want to keep it, remember that this is a one
time only type of macro and the first cell's results will only change if you
leave the original now formula intact. I would clean it up since it just
leaves something there that might cause a mistake.
If you need to make a macro in Excel 2007, make sure the developer tab is
showing. To make the developer tab show choose the Office Button and choose
Excel Options on the bottom of the drop down, check the Show Developer tab
in the ribbon.
Hope this helps,
