This article was previously published under Q170308


A user-defined Visual Basic for Applications function that carries out the Run method of the Application object (Application.Run) returns the #VALUE! error value.


Microsoft Excel enters recalculation mode when a user-defined function is called from a worksheet cell. While in recalculation mode, Application.Run is disabled.


To correct this problem, install Microsoft Excel 97 Service Release 1 (SR-1).

In Microsoft Excel 97, if you create a function that calls another user- defined function, call the function directly rather than using the Run method. (See the "More Information" section later in this article for sample code that demonstrates calling the function directly.)

There is no workaround if the user-defined function calls a function contained in a dynamic-link library (DLL or XLL). You must use Application.Run to call these functions.


Microsoft has confirmed this to be a problem in Microsoft Excel 97 for Windows. This problem was corrected in Microsoft Excel 97 SR-1.

For additional information about SR-1, please see the following article in the Microsoft Knowledge Base:

You can use the Run method of the Application object to run code written in the Visual Basic or Microsoft Excel 4.0 macro languages. You can also use the Run method to run functions contained in a DLL or XLL. With the exception of functions contained in a DLL or XLL, you can alternatively run functions by calling them directly from within another user-defined function as the following sample demonstrates.

  1. Open a new workbook.
  2. Press ALT+F11 to start the Visual Basic Editor.
  3. On the Insert menu, click Module.
  4. Type the following functions in this new module:

          Function X()
              X = 15
          End Function
          Function Y()
              'Call the user-defined function X.
              Y = X()
          End Function
  5. Type the following in cell A1 in Sheet1 of this workbook:

    A1: =Y()

    The value returned to cell A1 is 15 instead of #VALUE!.


For more information about user-defined functions, click the Office Assistant in the Visual Basic Editor, type user-defined function, click Search, and then click to view "Function Statement".
