need help programming value of proximity sensor to sweep servo arm

Sweet! This compiled. Is there a better way of writing this?

  if (vcnl.readAmbient() >100);
  TinyServo.write(90);
  {
    TinyServo.write(70);
  }

It's been close to 2 months since I ordered the servo. Should be here any day now. Then I can try it out. Don't have any servos just laying around.
