Using Hall Effect Sensors

[fireXtract]

Now i'm able to get the elevator to stop in response to the hall effect sensor, but once it use it to go up i cant press it to go up again, and if i go down i can only go down once. Pressing the button multiple times to add to count does nothing. What am i missing here?

		}

		if (count >= 1) {
			go = 1;
		} else if (count <= -1) {
			go = -1;
		}
		Robot.elevator.torro(go);

		if (count != 0) {
			done = false;
		} else if (count == 0) {
			done = true;
		}
		tcount = 0;
		SmartDashboard.putNumber("whaeva", count);
		SmartDashboard.putBoolean("hall", Robot.elevator.isHallSet());
	}

	// Make this return true when this Command no longer needs to run execute()
