Hi. I am making a database that includes a table that needs to keep records of deposits based on a bank id number and sum them up for a balance. I have fields Bank ID, Deposit, Balance, and Total. My idea is to make Total a summary field equal to Total of Deposit. Then I want to make Balance = GetSummary ( Total ; Bank ID). I had this working for a while and it worked exactly how I wanted it to. Now for some reason it does not work, and I cannot get it to work again. I have even tried making sample new databases to test it out and cannot get this function to work at all. Balance is just a blank field. Any help please?
