You've included Servo.h but you're not using any of its functions to drive your servo, which is why it won't move. Have a look at the Sweep and Knob examples in the IDE for how Servo.h is actually used. e.g.
Servo XXservo; // your servo name
XXservo.attach(pin); // pin it's connected to
XXservo.write(angle);
or
XXservo.writeMicroseconds(microseconds);
