I have this code in workbook#1

Global wb as workbook

sub dowhat()
wb.activate <<<< error here
...more code
end sub

============
and this code in a sheet of workbook#2

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count 1 Then Exit Sub
If Intersect(Range("B1:B20"), Target) Is Nothing Then Exit Sub

application.run "workbook1.xls!dowhat"
End Sub


The problem is that dowaht works if run from a macro in workbook#1 but not
when called from workbook#2 when a cell changes. The error I get is "Object
Required" which I assume is because "wb" is empty. Can someone please let me
know what I am missing.

thanks
