How do I create a unique identifier # when open excel file?

I have a purchase order spreasheet working with. I would like it to
automatically generate a unique identifier (PO number) upon opening the file;
is this possible? or some formula to automatically pull in the next
sequential #?

I have an invoices download at http://www.officearticles.com/downloads/
It does just what you want. Perhaps you can steal the code from it.

ritarowe, here is one way to do it, put in workbook open code

Sheets("Sheet1").Range("A1").Value = _

Sheets("Sheet1").Range("A1").Value + 1



If this is a temple have a look here for other ways to do it
