Two options:

Private Sub CommandButton1_Click()
Call macro1(Range("NamedRange1"))
End Sub

or

Private Sub CommandButton2_Click()
Dim myRng As Range
Set myRng = Range("NamedRange2")
Call macro1(myRng)
End Sub

I have written a macro that I would like to have operate the same way on

range of data as an input parameter, then I created several buttons that each
called the same macro, but with a different argument, as follows:

Private Sub CommandButton1_Click()
* * Call Macro1( "NamedRange1" )
End Sub

Private Sub CommandButton2_Click()
* * Call Macro1( "NamedRange2" )
End Sub

and so on. *However, I can't seem to find the right syntax for specifying a
range name in the call to the macro (if there is one). *Even if I have to use
cell references instead of a named range, I could live with that. *Does
anybody know if there is a way to do this?

Thanks!
