I am doing a database for purchasing items. It's not too complicated and very basic. I have the vendor's name, date, etc and a piece of equipment # like tele handler would be T-1 or T-2 etc. I have a total field for each PO. I want to be able to have a grand total of all the purchase orders per year. Can someone please help me on how to do that? Right now I need to now how to find a grant total of all the purchases for the year 2017. Is this difficult? I haven't added the field for Grand Total yet to the database. Thanks so much!
