Also, note that testing for 6 buyable quantities in a row is correct for 6, 9, 20 but is not necessarily correct for other denominations. You should think about how many you need to find in sequence for any given input of x, y, and z. Cheers, Ian -- http://mail.python.org/mailman/listinfo/python-list
