Sorry I don't understand that.
Not to worry there is no reason why I should.
However the bit I don't understand is:-
but I have changed LED to be 6
So quoting from:-
http://www.arduino.cc/en/Reference/PortManipulation
PORTB maps to Arduino digital pins 8 to 13 The two high bits (6 & 7) map to the crystal pins and are not usable
So I don't see how 6 could possibly work, you are targeting the wrong bit.
