You certainly can. However, I think we need a couple more details :)
As far as I can make out, you have some kind of arrangement like this
----------
| +3.23
| -2.43
| -4.51
| +94.45 <-- This is the NSTableView right?
| -324.53
| -1.28
-----------
======= <- And then you want an NSTextField down here that shows
the current balance of the transactions above
Is this right?
Almost, but more like this
Deposit | Debit
----------------------
10.00 |
| 23.45
100.00 |
So there are two distinct columns (all values are positive) and only
one can be occupied.

Hello list,
I am trying to learn Cocoa from a Java background. Currently
reading Hillegass's "Cocoa Programming" but I need some pointers
that he doesn't specifically mention.
I am writing a simple ledger program that relies on an NSTableView
for display. Via the chapter on binding I am using an
NSArrayController to take care of all the data management. My
dilemma is that I need to keep a single text field updated with
the current balance of an account. Can I do this using bindings
also, or should I use notification? I'm really at a loss of where
to go from here. TIA
