Last reviewed: September 12, 1996
Article ID: Q118797

The information in this article applies to:

Microsoft Excel for Windows, version 5.0

SYMPTOMS

In Microsoft Excel, if you use one of the functions provided in the Analysis ToolPak-Visual Basic for Applications add-in (ATPVBAEN.XLA), such as the EDATE() function, you receive the following error message:

   Run-time error '1004':

   Cannot find macro '[ATPVBAEN.XLA]REG!reg_EDATE'.

where the name of the function that you use appears in the place of EDATE in the above error message.

CAUSE

This error message appears when you use any of the following Analysis ToolPak functions in a Visual Basic module:

   New Function    Old Function
   ----------------------------

   EDATE           NEWMONTH
   EOMONTH         NEWMONTHE
   CUMIPMT         CUMPI
   TBILLEQ         TBILLYEQ
   TBILLPRICE      TBILLP
   TBILLYIELD      TBILLY

WORKAROUNDS

To avoid receiving this error message when you use one of these functions in a Visual Basic procedure, you can do either of the following:

Use the ExecuteExcel4Macro method to call these functions. To use this method, you must first open or load the Analysis ToolPak add-in, (ANALYSIS.XLL). You can then use the following example to access the EDATE function:

   Sub Test()
      Dim x as Date
      x = Application.ExecuteExcel4Macro("EDATE(datevalue(""1/1/94""),5)")
   End Sub

   NOTE: When you use this method with the EOMONTH() function, the value
   returned is one day less than the correct value. To avoid this
   problem, use the workaround below.

   -or-

Use the following custom functions in the place of EOMONTH() and EDATE().

   ' This function returns the serial number date for the last day of the
   ' month that is the indicated number of months before or after
   ' start_date.

   Function EO_Month(start_date, months)
      EO_Month = DateSerial(Year(start_date), _
        Month(start_date) + months + 1, 0)
   End Function

   'This function returns the serial number date that is the indicated
   'number of months before or after start_date.

   Function E_Date(start_date, months)
      Dim DaysInMonth As Integer
      DaysInMonth = Day(DateSerial(Year(start_date), _
        Month(start_date) + months + 1, 1) - 1)
      If Day(start_date) > DaysInMonth Then
         E_Date = DateSerial(Year(start_date), _
            Month(start_date) + months, DaysInMonth)
      Else
         E_Date = DateSerial(Year(start_date), _
            Month(start_date) + months, Day(start_date))
      End If
   End Function

   ' Example procedure using EO_Month function
   Sub Test1()
      Dim x As Date
      x = EO_Month(start_date:="1/1/94", months:="5")
      MsgBox x
   End Sub

   ' Example procedure using E_Date function
   Sub Test2()
      Dim x as Date
      x = E_Date(start_date:="1/1/94", months:="5")
      MsgBox x
   End Sub

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in Microsoft Excel for Windows version 5.0c.

Note that in Microsoft Excel version 5.0c, you only receive this error message when you use a function in ATPVBAEN.XLA if the file is not open when you run the procedure that contains the function.
