In access, I am trying to create a new document based on a template and then save the newly created document under a different name, in a different location.  The new document generates itself well, but when I try to open it, there is an error that pops up saying  The file test.docx cannot be opened because there are problems with the contents.    The code that I am using is below.  The strange thing is that when I remove the save as line and save the document manually, I can open the new document up without the error.  What can I do to fix this problem?

Private Sub ReportToWord(FileName, NewFileName)

On Error GoTo ReportToWord_err
    Dim objWord As Object
    Dim ContInf As String    
    
    Set objWord = Nothing
    Set objWord = CreateObject("Word.application")    

    objWord.Documents.Open FileName
    objWord.Visible = True

    objWord.activedocument.SaveAs NewFileName
    Set objWord = Nothing

ReportToWord_exit:
Exit Sub

ReportToWord_err:
    MsgBox (Err.Description)
    Set objWord = Nothing
    GoTo ReportToWord_exit
End Sub

Private Sub Invoice_Click()

    ReportToWord "Z:\Forms\Templates\ Invoice.dotx", "Z:\Repairs\" & InvoiceNumber & " " & BilledTo & ".docx"

End Sub
