I have a file that is used by another person in their directory.  When they
save the file I do various tests on values of certain range named cells and
if all the values are ok then that means the file is basically in good order
and I want a copy.  The issue is they sometimes mess up a file and don't
realize it until they have mess it up even more,  but it I can get a copy
when all test conditions are ok then I will always have the last good copy
handy.  I was hoping to do somethin like this:

Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)

If (Here are various tests and if OK) Then
   ActiveWorkbook.SaveAs Filename:="F:\Shared\Systems\Book3.xls",
FileFormat:= xlNormal, Password:="mybackup"
Endif

End Sub
And then it would go ahead and save their file in their directory.

Note:  I would alwasy like their file saved and only save to my directory if
all the tests are ok.  I have tried the above but excel errors totally out
where you get the message.  Do you want to send a report to Microsoft?

Is there a way to do what I want?

Thank you for your help.
