ran a quick sketch of my own..

void setup() {
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
// pinMode(9, OUTPUT);//dot
// digitalWrite(9, 1); // start with the "dot" off
}

void loop() {
delay(1000);
// write '3'
digitalWrite(2, 1);
digitalWrite(3, 1);
digitalWrite(4, 1);
digitalWrite(5, 1);
digitalWrite(6, 0);
digitalWrite(7, 1);
digitalWrite(8, 0);
delay(1000);

}

to make the 3 show... pin 7 had to be changed from 0 to 1 and 8 had to be changed from 1 to 0...

same with making the 2 show properly..

void setup() {
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
// pinMode(9, OUTPUT);//dot
// digitalWrite(9, 1); // start with the "dot" off
}

void loop() {
delay(1000);
// write '3'
digitalWrite(2, 1);
digitalWrite(3, 1);
digitalWrite(4, 0);
digitalWrite(5, 1);
digitalWrite(6, 1);
digitalWrite(7, 1);
digitalWrite(8, 0);
delay(1000);

}
