How do i stop the buzzing action once door sensor is opened (LOW)

Ok so @PaulS,

Let's say if i were to remove the else since it will make it complicated.. i changed it to else if and the condition is almost the same except for detecting the state of the switch which is HIGH, but after changing, i tried to run and it is almost the same with my previous code..

i tried to off the switch, it works by stopping the buzzer but once i on the switch, it continued to sound the buzzer (It started and ended the alarm perfectly, did not exceed nor ring before the alarm)

But i just want the alarm to stop once i OFF the switch (Which i dont want it to sound anymore)

void alarm1() //E.g. This is the first alarm for the medicine
{
  state = digitalRead(sensor);
  if( Hor == 20 && (Min == 11 || Min == 12) && state == 0) //Comparing the current time with the Alarm time
  {   
      Buzzer();
      
      lcd.clear();
      
      lcd.print("1st Alarm ON");
      
      lcd.setCursor(0,1);
      
      lcd.print("Morning Medicine");
      
     } 

  
  else if ( Hor == 20 && (Min == 11 || Min == 12) && state == 1)
  {
    noTone(buz);
  }
  delay(200);
}
