I need some help for this nuisance. I frequently use an Excel Spreadsheet with multiple Tabs. Every time I open the spreadsheet, I get a pop-up notice "Careful, we found one or more circular references in your workbook....." I can then open the spreadsheet with no problem and do whatever I have to do. I've manually searched for any cells with a formula and I can't find any with a circular reference. Any tips how I can identify the miscreant cell?
