Arrayformula to track Current Balance in Transaction Register
My sheet: 

Hi everybody,
My sheet will track a piano teachers lessons and payments. My challenge is to show Current Balance as students receive lessons and make payments.

I thought it would resemble a check register, but it got complicated by the fact that she has more than one student.

I've got a working formula in Column G – It calculates the current balance by looking at previous entries, and subtracting all payments from all fees as filtered by student the student entered on that row. But it's not an arrayformula, and I know she'll want to insert rows.
Anybody got any ideas?
