trying to test pushbutton

same wiring. did this. not working

#define BUTTON1 13

int buttonValue1 = 0;
int buttonValue2 = 0;

void setup(){
pinMode(BUTTON1, INPUT);
digitalWrite(BUTTON1, HIGH);
Serial.begin(9600);
}

void loop(){

buttonValue1 = digitalRead(BUTTON1);

if(buttonValue1 == HIGH){
Serial.println("OINK");
delay(10);
}
}

EDIT

have this now. but it perpetually prints "OINK" without me pushing the button.

#define BUTTON1 13
#define BUTTON2 12

int buttonValue1 = 0;

void setup(){
pinMode(BUTTON2, INPUT);
digitalWrite(BUTTON1, HIGH);
Serial.begin(9600);
}

void loop(){

buttonValue1 = digitalRead(BUTTON2);

if(buttonValue1 == HIGH){
Serial.println("OINK");
delay(10);
}
}
