so i was hoping that someone could help me with a bit of code. the project i am working on requires me to have 2 servos, that when a button is pushed, go in opposite directions. this is my code so far. however i cant seem to get another servo to work with it, any help would be greatly appreciated

State change detection (edge detection)
Often, you don't need to know the state of a digital input all the time,
but you just need to know when the input changes from one state to another.
For example, you want to know when a button goes from OFF to ON. This is called
state change detection, or edge detection.
This example shows how to use button state change to perform an action.
The circuit:
* Momentary pushbutton attached to digital pin 2 from +5V
* 10K resistor attached to digital pin 2 from ground
* Servo signal wire attached to digital pin 9
* Servo power wire connected to 5v
* Servo ground wire connected to ground
Based off the public domain "State Change Detection" example provided with the
Arduino software. Code edited 8-14-2011 by Will Lyon (SXRguyinMA) to remove
the LED and add in a servo.

// Include the servo library
#include <VarSpeedServo.h>
// Create a servo object to control a servo
VarSpeedServo myservo;
// this constant won't change:
const int buttonPin = 2; // the pin that the pushbutton is attached to
// Variables will change:
int buttonPushCounter = 0; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
void setup() {
// attach the Servo to pin 9
myservo.attach(9);
// make sure the servo starts off with the door closed
myservo.slowmove(180, 0);
// initialize the button pin as a input:
pinMode(buttonPin, INPUT);
}
void loop() {
// read the pushbutton input pin:
int buttonState = digitalRead(buttonPin);
// compare the buttonState to its previous state
if (buttonState != lastButtonState) {
// if the state has changed, increment the counter
if (buttonState == HIGH) {
// if the current state is HIGH then the button
// wend from off to on:
buttonPushCounter++;
}
else {
}
// save the current state as the last state,
//for next time through the loop
lastButtonState = buttonState;
}
// moves the servo every other button push by
// checking the modulo of the button push counter.
// the modulo function gives you the remainder of
// the division of two numbers:
if (buttonPushCounter % 2 == 0) {
myservo.slowmove(0, 180);
} else {
myservo.slowmove(180, 180);
}
