From: MIKEY on 28 Feb 2010 07:18 Hi all I want to automate Invoice numbers to my spreadsheets. I have saved the file as Read Only. When I open my Excell 2003 I enter client details. I want an invoice number allocated to this client upon being saved. When I open this client file the next day to update details I don't want the Invoice number to change. Is it possible to numeric Invoice numbers from a Read Only File, as I will only access this file when dealing with a new customer, and this is when I need the next invoice number Many thanks if you can help Mike
