    Invalid external reference to a worksheet (Excel 97)

    Probably a completely blonde question… but…!

    I have spreadsheet with a couple of pages of charts which all seem to work ok except for 1 of them. When I click Ion the tab it is located and more specifically when I right click on it to update or change the data source I get a pop up that says:

    Your formula contains an invalid external reference to a worksheet

    Verify that the path, workbook, and name range or cell reference are correct, and try again


    But I can’t find any references to any external worksheets in either the chart or the source data

    Also the parts of the source data I am using is being used by the other charts seemingly quite happily!

    I am using excel 97 (although the spreadsheet was created in a later version so I get a message every time I save it)

    Is there anything in excel 97 that I can use to find all external references so I can find the error as the annoying pop-up message is no help…it just tells me there is a problem but not how to find it!!

    Many thanks in advance

    Hi Rae - I saw some good links here Always make a backup copy 1st just in case something goes wrong.

    http://www.google.com/search?hl=en&q...nal+references

    Links also can lurk in objects, such as text boxes, autoshapes, etc. Objects can try to reference an external workbook. The easiest way to locate objects is to select any single cell on each worksheet and then select Edit -> Go To… (F5). From the Go To… dialog, click Special and then check the Objects option and click OK. This will select all objects on the worksheet. You should do this on a copy of your workbook. Then, with all objects selected, you can delete, save, close, and reopen your copy to see whether this has eliminated the problem.

    Finally, the last not-so-obvious place to check for real links is in the hidden sheets that you might have cleverly created and forgotten about. Unhide these sheets by selecting Format -> Sheet -> Unhide. If the Unhide option on the Sheet submenu is grayed out, that means you have no hidden sheets. (If you think there are sheets that don't turn up in the menu, see "Hide Worksheets So That They Cannot Be Unhidden" [Hack #5] for more information.)

    Now that you have eliminated the possibility of real links, it's time to eliminate the phantom links. Go to the haunted workbook with the phantom links and select Edit -> Links…. Sometimes you can simply select the unwanted link, click Change Source, and then refer the link back to itself. Often, though, you will be told that one of your formulas contains an error, and you will not be able to do this.

    Thanks ever so much for that

    It didn't actually work on this particular case as I apparently have no objects in my spreadsheet, but it did make me look more carefully at other options and areas

    I finally found it was a stupid error... the title of the chart was linked to a cell on a tab within the spreadsheet that was either moved or was now empty thus generating the lovely #REF indicator that excel loves to give me - hence the error message!

    But the F5 goto thingy will come in very handy in future as I have not used the special options before!

    Many thanks again

    Rae
