Press and hold a button for 2 seconds and it flashes

the code i posted was untested (i was traveling).
i'm home and when i tested it, it turned the led on and off, but it did not blink.
i corrected the problem and now it turns the led on, off and blinks if held for more than 2 secs but less than 3 (count mississippi)
