I am making a sales sheet for my schools business. We allow three forms of payment(Cash, Credit Card, and Debit Card). For every sale we record how much the total purchase was and how the customer paid in the same row albeit different column. I would like to add all purchases that have been purchased with cash separately from all purchases that have been purchased with credit and debit cards. Is there any formula or command I can use to sum up all values in the purchases column but exclude certain rows that have been purchased with credit and debit cards, or cash?
