There is a little bug I havent fixed yet. If, or when entering a second (or 3rd, etc) invoice price to calculate if you don't hit reset beforehand then you will have to cycle through the gst buttons untill the new price is reflected in the Invoice Cost + GST box or you will calculate on the old figure:)
