where can i get  information on errors?

Just in to this stuff in general. copied a script and pasted the complete thing ans a'm getting errors. Specifacly "no such file or directory in function" <AFMotor.h>,,,,AF_stepper does not name a type

It sounds like you are missing a header file in your sketch. Post the sketch, as your shoulder is blocking my view of your screen.

#include <AFMotor.h>

AF_Stepper motor(48, 2);

void setup() {
Serial.begin(9600); // set up Serial library at 9600 bps
Serial.println("Stepper test!");

motor.setSpeed(10); // 10 rpm

motor.step(100, FORWARD, SINGLE);
motor.release();
delay(1000);
}

void loop() {
motor.step(100, FORWARD, SINGLE);
motor.step(100, BACKWARD, SINGLE);

motor.step(100, FORWARD, DOUBLE);
motor.step(100, BACKWARD, DOUBLE);

motor.step(100, FORWARD, INTERLEAVE);
motor.step(100, BACKWARD, INTERLEAVE);

motor.step(100, FORWARD, MICROSTEP);
motor.step(100, BACKWARD, MICROSTEP);
}

When posting code be sure to use the # button in the message window to attach the proper tags. Be sure to download and install the library into the Library folder.

BTW your are using the AFmotor shield, right?
