Hello. I have a worksheet with my raw data on. I successfully created two PIVOT tables on new worksheets. I then deleted the worksheets with the PIVOT tables on because I wanted to start afresh. Excel won;t let me insert a new PIVOT table now. I get the error message "The PIVOTTable field name is not valid. To create a PIVOT Table report, you must use data that is organised as a list etc" That error messages seems irrelevant and wrong - my data was fine for a PIVOT table before, I haven;t changed it. It is simply that I deleted a worksheet with a PIVOT table on. I am bewildered. Thanks in advance for any insights you may have. My issue has nothing to do with columns or column headers or lists or empty headers.
