Hello bobhc:
I constructed the original workbook, which is why I assumed that the file path (which does not exist) may have been a draft that I created last year. Fortunately, I did not have to clean up the data source. The data source was fine - the only place where I had duplicates was in the drop down lists for the PivotTable and the Slicer (Two for January 2012 when there should have been only One for January 2012). To make sure that there were no hidden duplicates in the Data Source, I deleted all of January 2012 but the duplicate January 2012 stayed in the PivotTable and Slicer drop down lists: That is what was so frustrating about this. I could not get rid of that duplicate. So I decided to make a new PivotTable, which was a pain, but now it is working fine. It seemed odd to me that I could "Refresh" but when I tried to "Refresh All" I got a message telling me that Excel could not open the data source file. Question: If Excel could not open the data source file, why was Excel "Refreshing" when I added data to my table? I sure hope that I will feel the same as you do about 2013. I am looking forward to it. Thank you for your consideration and support.
