buttonStateR = digitalRead(buttonR);

if (buttonStateR == HIGH);{

    buttonState4 = digitalRead(button4);
    
       while (buttonState4 ==HIGH){
        
        tone(buzzer,450);
        delay(1000);
        noTone(buzzer);
        delay(1000) ;
       }            
            digitalWrite(led_red, HIGH);
            delay(500);
            digitalWrite(led_red, LOW);
            delay(500);
          
            digitalWrite(led_ylw, HIGH);
            delay(500);
            digitalWrite(led_ylw, LOW);
            delay(500);
          
            digitalWrite(led_grn, HIGH);
            delay(500);
            digitalWrite(led_grn, LOW);
            delay(500);
            
              tone(buzzer, 450);
              delay(500);
              noTone(buzzer);
              delay(500);
            
              tone(buzzer, 450);
              delay(500);
              noTone(buzzer);
              delay(500) ;
           
              tone(buzzer,450);
              delay(500);
              noTone(buzzer);
              delay(500) ;

}
else {
state = 0;
}

I always get the Error:
'else' without a previous 'if'

why is this?
