I have a list of Invoices with a Date and Email Addresses from a sales database.
I have counted the number of invoices per email address...but now I need to mark each invoice as "First / Second/Third, Fourth, Fifth Order .. basically what sequence....
I am trying to calculate the number of days on average between a customer's first order and 2nd order...
How do I post a photo ?
