Arduino servo control

Hi,
This is my first post and I am just starting to learn arduino.
I'm trying to figure out how to set a servo positions by push three or four buttons. For example, button 1 = position A, button 3= position C, etc.
Can anyone help?
Thanks in advance!

Learn how to read a button: http://arduino.cc/en/tutorial/button

Learn how to position a servo: Servo - Arduino Reference

Connect those two together with some programming.

Servo/button test code.

//zoomkat servo button test 12-29-2011
// Powering a servo from the arduino usually *DOES NOT WORK*.

#include <Servo.h>
int button1 = 4; //button pin, connect to ground to move servo
int press1 = 0;
int button2 = 5; //button pin, connect to ground to move servo
int press2 = 0;
Servo servo1;

void setup()
{
  pinMode(button1, INPUT);
  pinMode(button2, INPUT);
  servo1.attach(7);
  digitalWrite(4, HIGH); //enable pullups to make pin high
  digitalWrite(5, HIGH); //enable pullups to make pin high
}

void loop()
{
  press1 = digitalRead(button1);
  if (press1 == LOW)
  {
    servo1.write(170);
  }    
  
  press2 = digitalRead(button2);
  if (press2 == LOW)
  {
    servo1.write(10);
  }
}

  pinMode(button1, INPUT);
  pinMode(button2, INPUT);
  servo1.attach(7);
  digitalWrite(4, HIGH); //enable pullups to make pin high
  digitalWrite(5, HIGH); //enable pullups to make pin high

What happened to the names? Why did pins 4 and 5 go back to being numbers.
