Financial calculation based on date and department

[LoffKat]

Hello, I am trying to create a field that will sum data from another related table.

I have 5 tables, one for event info, one for daily individual costs by event and date, one for daily totals by event and date, one for event totals by event, one for accounting totals by event.

The daily individual costs have a department field and various other financial information. In the Daily totals table I would like the department field to calculate the total of the individual costs broken down by department. (for ex: all operations expenses for the specific date would total in the daily operations field in the daily totals table)

I am not sure how to do this and am confused by sum field field input that comes up. I need the sum to be calculated for department by date. please help. any help would be greatly appreciated. thank you.

Can you elaborate on how your process is for what you are trying to do? From what you posted, it does not seem like you need 5 tables.
