Its probably because u r using =month(now())-1, this equates to Jan - 1,
which although Jan minus 1 month is Dec, Excel interprets as 1-1 = 0 (i.e.
Jan -1). Hence the case select does not work as there is no branch for zero.
Try
Select Case DATE(YEAR(NOW()),MONTH(NOW())-1,DAY(NOW()))

Its untested may not work as code but its work as an excel formula so should
convert easy enough.

I have a routine that uses the name of the workbook to create a new workbook
for the current month. It has worked perfectly through the year til now.
Maybe it has something to do with the change of the year?

Old workbook name = JOHN REPORT Nov 04 - WB w/macro to create new WB
New workbook name should be = JOHN REPORT Dec 04
Actual name the routine creates now is = JOHN REPORT 04 - with no month.

The code is:

tmpName = Left(ActiveWorkbook.Name, Len(ActiveWorkbook.Name) - 10)

Select Case Month(Now()) - 1
Case 1
tmpMonth = "Jan "
Case 2
tmpMonth = "Feb "
Case 3
tmpMonth = "Mar "
Case 4
tmpMonth = "Apr "
Case 5
tmpMonth = "May "
Case 6
tmpMonth = "Jun "
Case 7
tmpMonth = "Jul "
Case 8
tmpMonth = "Aug "
Case 9
tmpMonth = "Sep "
Case 10
tmpMonth = "Oct "
Case 11
tmpMonth = "Nov "
Case 12
tmpMonth = "Dec "


End Select

tmpYear = Right(Year(Now()) - 1, 2)

ActiveWorkbook.SaveAs Filename:="C:\Documents and
Settings\Name\MyDocuments\PRC JOHN\" _
& tmpName & tmpMonth & tmpYear, _
