I want to sum the number from a column put in a template named "Order Form" to an other workbook named "Database Order". I need to see for every order I do how many time a picece was ordered.
I hope that now is more clear. Anyway, Take a look to the image please.
The "code number" is "Identity" number; and the "quantity" change every time I do an Order (for a customer).
The thing that I need is to sum automatically the quantity of every piece , in an other workbook ("Database Order"), every time I wright an order.
