XL2000: Error Getting the Value of a Name in Visual Basic

View products that this article applies to.

This article was previously published under Q213655

Symptoms

In Microsoft Excel, you may receive one or more of the following error messages when you use the Range(Name).Value method in Microsoft Visual Basic for Applications to get a value based on a defined name.

Run-time error '1004':
Method 'Range' of object '_Global' failed

-and-

Run-time error '13':
Type mismatch

Cause

This problem occurs if the defined name in question refers to a constant value or a formula rather than a range.

Resolution

To prevent the error message from appearing, use the Evaluate method to determine the value of the defined name. Please see the "More Information" section of this article for an example that demonstrates this issue.

More information

If a particular defined name refers to a constant value or a formula, you can use the .Evaluate(Name) method to get the value of the name. The .Evaluate(Name) method can evaluate formulas and constant values even if they don't refer to an actual range.

However, note that the .Evaluate(Name) method may return an error message if the name refers to an error value, such as #REF! or #N/A. In these cases, you may need to employ error checking (such as the On Error Resume Next function) or use an alternative method, such as the Names(Name).RefersTo method, to detect or handle an error value.

For example, if you have a sheet named Sheet1 in a workbook that contains the following global names

   This
   Name     Refers to               Cell information
   ---------------------------------------------------------------
   Alpha    =Sheet1!$B$1            Cell B1 contains the number 1
   Bravo    =2
   Charlie  =SUM(Sheet1!$B$3:$C$3)  Cell B3 contains the number 3
                                    Cell C3 contains the number 4
   Delta    =Alpha
   Echo     =Charlie
   Foxtrot  =Alpha+Charlie
   Golf     =#N/A

and you use the Range(Name).Value and .Evaluate(Name) methods to get the values of the names, you receive the following results in your macro:

   Name     Range(Name).Value     Sheets("Sheet1").Evaluate(Name)
   --------------------------------------------------------------
   Alpha    1                     1
   Bravo    [Error message 1]     2
   Charlie  [Error message 1]     7
   Delta    1                     1
   Echo     [Error message 1]     7
   Foxtrot  [Error message 1]     8
   Golf     [Error message 1]     [Error message 2]

NOTE: Error messages 1 and 2 are as follows:

Error Message 1

Run-time error '1004':
Method 'Range' of object '_Global' failed

Error Message 2

Run-time error '13':
Type mismatch

Sample Visual Basic Procedure

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to 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 requirements.

Check the Value of a Name

To check the value of a name, you can use the following subroutine:

Option Explicit
Sub CheckNameValue()
   Dim Test As Variant
   Test = Range("Alpha").Value
End Sub

To check the value by using .Evaluate(Name), use

   Test = Sheets("Sheet1").Evaluate("Alpha")

in place of the previous test line.

MsgBox Test

In order to prevent an error when the name refers to an error value (in this case, if the name is Golf), use the Names(Name).RefersTo method to check the name before getting its value. For example, you could use:

Sub CheckForError()
   'If the name Golf refers to an error value, such as #REF! or #N/A,
   If IsError(Evaluate(Names("Golf").RefersTo)) Then
      'then show an error message to that effect,
      MsgBox "Golf is an error name!"
   Else
      'otherwise state that the name refers to a good reference.
      MsgBox "Golf is OK!"
   End If
End Sub

If the name refers to an error value, the IsError test is true and the error message box is displayed. Otherwise, the OK message box is displayed. For example, if the name is Golf, which refers to =#N/A, the error message box is displayed. Using any of the other example names results in the OK message box.
