Bill,
I've spent considerable time inputting a large and varied amount of data into HFE for my wife...made mistakes along the way, discovered features by trial and error, offerred a number of suggestions and so forth. This is a good application and well worth taking the time to become familiar with it. There is much to be learned from this forum as well....if you haven't, consider entering some search words to find posts previously discussed on topics of your interest.
