Reference to ATPVBAEN.XLS
 

I can't find out how to refer to the Regress function of ATVBAEN.XLS in Excel
2007, which we just converted to. Here's the old code that used to work in
Excel 2003:

'Run regression
Application.Run "ATPVBAEN.XLA!Regress", Range("Mgr"), Range("Index"),
False, False, , Sheets("Regression").Range("$A$1"), False, False, False,
False, , False

Excel 2007 doesn't know what this file is. Thanks for your help.
