Circular Reference?

[Jennie]

I think this may be a stupid (or at least simplistic) question, but here goes:

I'm trying to create a calculation (I think) to keep a running total (of publications requested, if that matters).

So I have a field that I would be inputting into, called "Requested". And I have field called "Total".

Basically, I was trying to set up the "Total" field as a calculation (in Define Fields); the calculation I put in was Total + Requested, but I get a message telling me that I can't do that because it would create a circular reference (shades of Excel!).

I figure this is either something that I really can't do, or I'm missing something verrry basic (I'm a bit new at this, if you couldn't tell). What to do?

Hi Jennie,

sipmly use a third field in which store the calc.

A field cannot involve himself in a calc. (as you noted in Excel).
