Circular reference toolbar not working

[inews]

If I create a circular reference purposely, the circular reference
toolbar does not appear and no warning is displayed.

The "Formula Auditing" toolbar's Evaluate Formula button correctly
identifies the circular reference, but when I force the "Circular
Reference" toolbar out of hiding (customise, etcetera), the "Navigate
Circular Reference" combo box is empty. It remains empty even when I
select or activate the cell containing the circular reference.

The reference needn't be anything complex.
E.G.
A1 = A2
A2 = A1

Iterations are working. EG 500 iterations increases the values by 1000

Automatic calculation is also working fine.

Excel 2002 SP3.

How can I get the Circular Reference toolbar to function correctly?

Nevermind.

It seems the Circular Reference error/toolbar is not shown when
iterations are turned on and this dependency is not documented in the
help file.

Hi!

Iterations are working. EG 500 iterations increases the values by 1000

If you set iteration *before* you actually create the circular reference
(either intentional or accidental) you'll get no warning but you should see
"Calculate" in the Status bar.

If you create the circular reference without setting iteration then you'll
get the pop-up warning. If you select "OK" from the warning dialog then the
toolbar opens.

Thanks Biff. That matches what I have seen now.

The relevant circular reference was only counting the cells in a column
above a rolling point from a fixed point, including the current cell,
as a condition for determining which of two formulae to use in order to
produce a discontinuous function. So the actual calculation (aside
from the choice of which to use) was unaffected by the circular
reference. I can understand why the circular reference subsystem would
leave out the nuance of whether an end calculation was affected - too
many possibilities.

In the end, I excluded the current cell from the count and added 1.
Same effect, no more circular reference!
