XL98: #VALUE! Appears When Function Is RecalculatedLast reviewed: February 2, 1998Article ID: Q178435 |
The information in this article applies to:
SYMPTOMSIn Microsoft Excel 98 Macintosh Edition, cells that contain formulas that refer to user-defined functions may return a #VALUE! error after you run a Microsoft Visual Basic for Applications macro or perform any action that causes the worksheet that contains the formulas to be recalculated. Also, if a Visual Basic subroutine is running when the formulas are recalculated, the subroutine may stop without warning.
CAUSEThese problems may occur if an error occurs in a user-defined function while the worksheet is recalculated. For an example of this problem, see the "More Information" section of this article.
WORKAROUNDMicrosoft provides programming examples for illustration only, without warranty either expressed or implied, including, but not limited to, the implied warranties of merchantability and/or fitness for a particular purpose. This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific needs. If you have limited programming experience, you may want to contact the Microsoft fee-based consulting line at (800) 936-5200. For more information about the support options available from Microsoft, please see the following page on the World Wide Web:
http://www.microsoft.com/support/supportnet/refguide/default.aspTo work around this problem, press COMMAND+SHIFT+F9 to force the values to be recalculated. When you do this, any formulas that refer to user-defined functions are recalculated correctly. To prevent this problem from occurring, add error-handling code to your user-defined function, as in the following example:
Function MyFunction(CellRange As Object) As String On Error GoTo ErrorHandler 'new line If CellRange.Interior.Pattern = xlNone Then MyFunction = "yes" Else MyFunction = "no" End If Exit Function 'new line ErrorHandler: 'new line MyFunction = "error" 'new line End FunctionIn this user-defined function, the line "On Error GoTo ErrorHandler" causes the function to continue if an error occurs. In this case, the error- handling code causes the function to return a value of "error", instead of "yes" or "no" or #VALUE!. After the formulas return "error", press COMMAND+SHIFT+F9 to recalculate the worksheet.
STATUSMicrosoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
MORE INFORMATIONIn Microsoft Excel 98 Macintosh Edition, if a user-defined function returns an error value, the formula that called the user-defined function and any other formulas that call the same user-defined function may fail to be recalculated properly. When this happens, the formulas may return a #VALUE! error. Also, if the user-defined function returns an error value, any running Visual Basic subroutine that caused the recalculation to occur may stop. This may cause problems if the subroutine is running unattended. To see examples of these problems, follow these steps:
