unique sequential number excel 2000
 

I have multiple sheets in a workbook which I am using as stock records.
I have a macro which hides certain rows on the worksheet (which are not
required on the Issue Voucher) and prints out a copy of the worksheet stock
record as an Issue Voucher to two separate printers. I want to put in a
sequential number on the Issue Voucher, each time I run a print. Help! Can I
write something into the macro?
