Problem with Motor Shield

I built my motor shield today :slight_smile:

Moved onto the next step sending it code to do something fun, and I get an error with the lib, when I try to compile.

I downloaded it from:
http://www.arduino.cc/playground/ComponentLib/Servo

------------------------------ My Code --------------------------------
#include <ServoTimer1.h>

ServoTimer1 servo1;
ServoTimer1 servo2;

void setup() {
Serial.begin(9600); // set up Serial library at 9600 bps
Serial.println(“Servo test!”);
servo1.attach(10);
servo2.attach(9);
}

void loop() {
Serial.print(“tick”);
servo1.write(180);
servo2.write(0);
delay(1000);

Serial.print(“tock”);
servo1.write(0);
servo2.write(180);
delay(1000);
}


The Errors are below.

Thank you for the help getting this working.

It looks to me like you've installed the servo library in the wrong directory.

I placed the lib in the directory shown at link: http://www.ladyada.net/make/mshield/download.html
