I recently took a large workbook and split several of the pages. I took some charts from one page and put them on another. Then I went through and updated all my formulas and all my named ranges. However, I am still getting a message that states "a formula in this worksheet containes one or more invalid references. Verify that your formulas contain a valid path, workbook, range name, and cell reference." I have looked through the spreadsheet many times, and cannot find the problem. Excel is not highlighting the problem forumla, and I cannot find the #REF anywhere. I've tried everything I can think of and I can't find the problem. Can anyone help me?
