I'm really new to the macros in excel, but I'm looking for something that will allow me to automatically generate a sequential number that can be used for an invoice or PO number. Once it uses the number it will go to the next number. I hope I'm clear in what I need, basically I have a PO form and everytime I open up a new form I want a new number in PO # box on the form. Could you also please either tell me or link me how to set-up the macro to get it working. Thanks!
