came across this dual servo sketch for controlling a webcam. http://translate.googleusercontent.com/translate_c?hl=cs&rurl=translate.google.com&sl=cs&tl=en&twu=1&u=http://blog.tomasbrincil.cz/%3Fp%3D316&usg=ALkJrhgbq-lUj7jqgEIQmTa39TeiMaM9Wg

Here you are this compiles:-

  #include <Servo.h>
 Servo servoX;
 Servo servoY;
 int input = 0;
 int x = 90;
 int y = 90;
 int one_step = 5;

 void setup () {
   servoX. attach (9);
   servoY. attach (10);
   servoX. write (x);
   servoY. write (y);
   Serial.begin (9600);
 }

 void loop () {
   if (Serial. available ()> 0) {
    input = Serial.read ();
     // UP
     if (input == 56 && y <180) {
       y = y + one_step;
       servoY.write (y);
     }
     // DOWN
     if (input == 50 && y> 0) {
       y = y - one_step;
       servoY.write (y);
     }
     // LEFT
     if (input == 52 && x <180) {
       x = x + one_step;
       servoX.write (x);
     }
     // RIGHT
     if (input == 54 && x> 0) {
       x = x - one_step;
       servoX.write (x);
     }
   }
 }
