add the following code to the report's module, as
Private Function isModified(ByVal str As String) As String
isModified = CurrentProject.AllReports(str).DateModified
End Function
in report Design view, add an unbound textbox control and set its'
ControlSource property to
=isModified([Name])
make sure you don't have a field in the report's RecordSource called Name
(you shouldn't anyway, because Name is a reserved word in Access).
