I'm new to VBA with Excel. I was wondering how I can have a unique Invoice Number printed on an expense report I have created. It is in a protected Excel 97 template. There will multiple users and I need the invoice number counter to increment by one each time the template is opened. I'm sure some one has run into this before. If the code exists please let me know where to find it. I'm very familiar with VB just not the Excel API.
Thanks for your help in advance,
