I'm trying to make a program that whenever a button is push, a different word will show on a lCD screen. However, it seems that the two buttons provide the same output ("Screen A"), it's like there is no difference between them, and I'm not sure what's the cause.

The code is very simple:

void loop() {

  for(int x=0; x<2; x++)
  {
    buttonState = digitalRead(buttonPin[x]);

    if (buttonState == HIGH && buttonPin[x] == 13) {
      lcd.print("  Screen A ");
    }
    if (buttonState == HIGH && buttonPin[x] == 12) {    
      lcd.print("  Screen B ");
    }
  }
  
}

Any help is appreciated
