Controling sound using potentiometer and button

void setup() {
  // put your setup code here, to run once:
pinMode(buzzer,OUTPUT);

}

void loop() {
  // put your main code here, to run repeatedly:
buttonState1 = digitalRead(button);
val=analogRead(potpin);
Serial.println(val);
tone(buzzer,val);
if(buttonState1==HIGH){

  delay(20);
