We no longer have Lotus 123 at work (even though 123 is VASTLY SUPERIOR to Excel), but I recall having referenced the filename in headers. I believe you use the "\\" characters, followed by a range name. In the cell named with the range name, use the @CELL(filename) command which I believe will also include the sheetname. If you want to isolate the sheetname, use the String functions (@MID or @RIGHT) --- or perhaps there is a separate function for the sheetname - such as @CELL(sheetname). ...hope this helps ...Dale Watson
