Relay Control: 4 Relays, 4 Pushbuttons

Thanks Tom. I think I got it figured out. I tried this code and it seems to work.

int relay1 = 13; //Amp CH1 relay
int relay2 = 12; //Amp CH2 relay
int relay3 = 11; //Amp CH3 relay
int relay4 = 10; //Amp CH4 relay
int button1 = 2; //CH1 Button
int button2 = 3; //CH2 Button
int button3 = 4; //CH3 Button
int button4 = 5; //CH4 Button
void setup()
{
  // Initialize digital output pins for relays:
pinMode(relay1, OUTPUT);
pinMode(relay2, OUTPUT);
pinMode(relay3, OUTPUT);
pinMode(relay4, OUTPUT);
pinMode(button1, INPUT_PULLUP);
pinMode(button2, INPUT_PULLUP);
pinMode(button3, INPUT_PULLUP);
pinMode(button4, INPUT_PULLUP);
}

void loop()
{
  bool button1State ;
  button1State = digitalRead(button1);
  if(button1State == LOW)
  {
    digitalWrite(relay1, LOW);
    digitalWrite(relay2, HIGH);
    digitalWrite(relay3, HIGH);
    digitalWrite(relay4, HIGH);
  }
  bool button2State ;
  button2State = digitalRead(button2);
  if(button2State == LOW)
  {
    digitalWrite(relay2, LOW);
    digitalWrite(relay1, HIGH);
    digitalWrite(relay3, HIGH);
    digitalWrite(relay4, HIGH);
  }
  bool button3State ;
  button3State = digitalRead(button3);
  if(button3State == LOW)
  {
    digitalWrite(relay3, LOW);
    digitalWrite(relay1, HIGH);
    digitalWrite(relay2, HIGH);
    digitalWrite(relay4, HIGH);
  }
  bool button4State ;
  button4State = digitalRead(button4);
  if(button4State == LOW)
  {
    digitalWrite(relay4, LOW);
    digitalWrite(relay1, HIGH);
    digitalWrite(relay2, HIGH);
    digitalWrite(relay3, HIGH);
  }
}
