Add New Worksheet through VBS COM Object
 

I have a problem when I try to add a worksheet through the EXCEL COM object
it adds Sheet4 in front of Sheet1, Sheet2, Sheet3. I want it to add the
sheet at the end of the sheets. The following code does not work from a .vbs
external script.
Excel Code:
ActiveWorkBook.Sheets.Add after:Worksheets(Worksheets.Count)

I have tried externally:
ExcelApp.WB.Sheets.Add (after:=Sheet3)

What to put in statement after Add?
