Hi all, this is a spread sheet utility with numerous routine & practical calculations put to a spread sheet. I've had this locked away in a file storage and thought maybe someone could get some use of it. I think I spent a years worth of saturday mornings putting it together. There is a cell reference index to tell you where to find a subject. Once loaded, use Ctrl + F and select the "Go to" tab to find the cell - as per the cell index - . Anyway, try it!
