Hi.

I have a workbook that displays "Circular references" in the lower left
corner.
I have checked each worksheet but the message does not change to include the
cell reference containing the error on any of them.
I have checked that there are no hidden sheets (including Excel Very Hidden).

Does anyone have any ideas about how to proceed?

I can't install new software or add-ins as that is a sacking offence.

Regards

Phil
