My nonexistent skills aren't up to even this simple task 
I need a simple Excel table: column 1: regular incomings; column 2: regular outgoings (standing orders, DDs, petrol, food, etc); column 3: running balance.
But I need/want to be able to add in miscellaneous outgoings, and to be able to see what effect that's going to have on the month ahead, if you see what I mean. So I can see what my balance is/will be in any given day in the month ahead.
Can anyone tell me what formulae to put where, pretty please?
(Of course, if there's an app that does this, that would be grand.)
