Confusion about none working Interrupt 2 on a ATMega644P/1284P

Yep Jack, That's what I did - it's a bit room 101 but here is the code

const int MotorLED1 = A5;
const int MotorLED2 = A7;
const int MotorLED3 = 13;

void setup()
{
pinMode(MotorLED1,OUTPUT);
pinMode(MotorLED2,OUTPUT);
pinMode(MotorLED3,OUTPUT);

attachInterrupt(0, Motor1, FALLING);
attachInterrupt(1, Motor2, FALLING);
attachInterrupt(2, Motor3, FALLING);
}

void loop()
{
delay (300);
digitalWrite(MotorLED1, LOW);
digitalWrite(MotorLED2, LOW);
digitalWrite(MotorLED3, LOW);
}

void Motor1()
{
    digitalWrite(MotorLED1, HIGH);
}
void Motor2()
{
    digitalWrite(MotorLED2, HIGH);
}
void Motor3()
{
    digitalWrite(MotorLED3, HIGH);
}
