XL97: Compile Error Passing ParamArray (157351)
The information in this article applies to:
- Microsoft Excel 97 for Windows
This article was previously published under Q157351 SYMPTOMS
If you are passing a ParamArray to another function, you may receive the
following error:
Compile error:
Invalid ParamArray use
CAUSE
This error message may occur if both of the following conditions are true:
- You are running your macro code in Microsoft Excel 97.
-and-
- You are passing the ParamArray to a ByRef argument in another function.
NOTE: If you run the same macro code in Microsoft Excel versions 5.0 or
7.0, you will not receive the error message.
You receive the compile error because Visual Basic for Applications in
Microsoft Excel 97 does not allow you to pass a ParamArray to a ByRef
argument in another function.

To work around this problem, add "ByVal" (without quotation marks) to the
argument receiving the ParamArray in the function that is being called.
For example, the following macro code returns an error when you run the
"Test" subroutine:
Sub Test()
x = myfun(1)
MsgBox x
End Sub
Function myfun(y As Integer, ParamArray myarr() As Variant) As Integer
myfun = otherfun(y, myarr)
End Function
Function otherfun(y As Integer, myarr As Variant) As Integer
otherfun = y * 2
End Function
If you change the "otherfun" function declaration to
Function otherfun(y As Integer, ByVal myarr As Variant) As Integer
and run the "Test" subroutine, you get a message box with a value of 2
displayed.
STATUS
Microsoft has confirmed this to be a problem in the Microsoft products
listed at the beginning of this article.
MORE INFORMATION
When you have an argument in the argument list of a function and you do not
specify either ByVal (by value) or ByRef (by reference), the argument will
be ByRef. This is the default in Visual Basic for all variables.
