Hi,

Here is a macro that I have posted a couple of time here and I think that it
will do what you want. Fee free to get back to me if it need a little
tweeking.

Sub Save_As_NewName()
Dim strInitName As String
Dim strNewName As String
Dim intAppend As Integer
Dim myFile As String
Dim strPath

'Set the next line to required file path
strPath = Application.DefaultFilePath
'Note next two variables start with same value
strInitName = strPath & "\Book1"
strNewName = strInitName

Do
   'Dir function searches for the file description
   'which has been concatenated from strNewName
   'plus the file extension (First search is for
   '"C:\Book1.xls")
   'if file found then myFile = filename so
   'therefore it exists. If not found then myFile
   'is empty or = ""
   
   myFile = Dir(strNewName & ".xls")
   
   'If myFile is not empty then increment intAppend
   'and concatenate it with strInitName and save the
   'concatenated string to strNewName so on the first
   'loop strNewName would become "C:\Book11".
   'Note that strInitName remains unchanged.
   'On the next loop if "C:\Book11" exists then
   'strNewName would become "C:\Book12".
   If myFile <> "" Then
       intAppend = intAppend + 1
       strNewName = strInitName & intAppend
   End If
   If intAppend > 3 Then
       MsgBox "Already " & intAppend & _
           " saves of this file" & Chr(13) & _
           "Processing terminated"
           'Insert your code here to handle the
           'excessive saves.
           End
   End If
           
   'Next line will cause the code to loop if myfile
   'is not empty. If myFile is empty then it has not
   'found the most recent strNewName therefore it does
   'not exist and can be used as the new file name.
   
Loop While myFile <> ""

ActiveWorkbook.SaveAs Filename:= _
       strNewName, FileFormat _
       :=xlNormal, Password:="", WriteResPassword:="", _
       ReadOnlyRecommended:= _
       False, CreateBackup:=False

End Sub
