Did you notice that my previous post had a Link to information on how to implement this "pre-population", along with a discussion on why it was not a good idea ?

Actually this is a different form of pre-population..if NONE is entered it should just skip that screen and move on...and if SCRAP is entered it should skip that screen also...since all input is being sent to a data file anyways. So in actuality there's no need to even show a Loaded or Empty screen. It does help to talk things out in order to solve a problem.
