WORKAROUND
Microsoft provides examples of Visual Basic for Applications procedures for

provided 'as is' and Microsoft does not guarantee that they can be used in
all situations. While Microsoft support professionals can help explain the
functionality of a particular macro, they will not modify these examples to
provide added functionality, nor will they help you construct macros to
meet your specific needs. If you have limited programming experience, you
may want to consult one of the Microsoft Solution Providers. Solution
Providers offer a wide range of fee-based services, including creating
custom macros. For more information about Microsoft Solution Providers,

The following workarounds assume that you have a Visual Basic module that
contains two macros:
Sub Macro1()
Dim X As Variant
X = ActiveWorkbook.Sheets("Sheet1").Range("A1:A5")
Macro2 X(1, 1) ' X is an array of type Variant...
End Sub
Sub Macro2(Y As Integer) ' ...but Macro2 expects an Integer.
MsgBox Y
End Sub
When run, the first macro (Macro1) initializes an array named X, populates
the array, and then sends a value from the array to the second macro
(Macro2). Macro2 then displays the value in a message box. If you run
Macro1 without applying any of the following workarounds, you will receive
the error message mentioned in the "Symptoms" section.
Method 1
To prevent the problem from occurring, change how the second macro (Macro2)
accepts values. In this case, change the second macro to
Sub Macro2(Y As Variant) ' Y is now a Variant, not an Integer.
MsgBox Y
End Sub
to eliminate the problem, because an element from an array of type Variant
is being sent to a variable of type Variant.
Method 2
A second way to prevent the problem from occurring is to convert the value
to an Integer as you pass it to the second macro using the CInt function.
Sub Macro1()
Dim X As Variant
X = ActiveWorkbook.Sheets("Sheet1").Range("A1:A5")
Macro2 CInt(X(1, 1)) ' Convert Variant X(1, 1) using Cint.
End Sub
Sub Macro2(Y As Integer) ' Macro2 expects an Integer.
MsgBox Y
End Sub
Method 3
Another way to prevent the problem from occurring is to dimension a second
variable in the first macro. This second variable should be of the same
type as the value accepted by the second macro. The value from the array is
copied into the second variable, which is then sent to the second macro.
For example:
Sub Macro1()
' Z is the second variable. It is an Integer, just like Y.
Dim X As Variant, Z As Integer
X = ActiveWorkbook.Sheets("Sheet1").Range("A1:A5")
Z = X(1, 1) ' Get the value from the array and put it in Z.
Macro2 Z ' This works correctly.
End Sub
Because Z is an Integer, the value of Z is received by Macro2 (which
expects an Integer) correctly.
