I use an Excel invoice to bill clients.
Currently I have an Invoice Date field which is populated by the
=TODAY() function. That's good. However, if I open the spreadsheet down
the road and accidentally recalculate, the Invoice Date field is
updated with the current date. That's not so good.

Is there a simple macro I can use that Inserts the date when the
document is created and then terminates? Something, I guess, that calls
the TODAY() function and then pops the resulting date value into the
appropriate cell.

I know I can just use CTRL+; to insert the date manually but I'm
shooting for *fewer* things that I can potentially forget when
invoicing.

Thanks,

KZ
