Ah, the classic percent confusion. You have to keep in mind what is considered 100 percent. If you have 1 dollar and get another, you'd have increased your fortune by 100 percent, leaving you with 2 dollars. But if you have 240 dollars and get another, you'd only had your fortune increased by 0.4 percent. anders ------------------------- http://anders.hultman.nu/ med dagens bild och allt!
