Probleme mit einfacher Tasterschaltung

[achso]

Danke Euch Allen!
Nun dachte ich, es wäre Einfach.
War aber nichts.
Dieser Code schaltet so lange man den Taster hält:

*/
const int ledPin_1    = 8;
const int ledPin    = 13;
const int Pin = 6; // Taster
const int Pin_1 = 7; // Taster

void setup()
{
  pinMode(6, INPUT);
  pinMode(7, INPUT);
  pinMode(13, OUTPUT);
  pinMode(8, OUTPUT);
}

void loop()
{
  int Taster = digitalRead(6);//Taster A
  while (Taster == 1)//while the button is pressed
  {
    digitalWrite(13, HIGH);
    delay(10);
    digitalWrite(13, LOW);

    Taster = digitalRead(6); //refresh value of variable
  }



  {
    int Taster_1 = digitalRead(7);//Taster B
    while (Taster_1 == 1)//while the button is pressed
    {
      digitalWrite(8, HIGH);
      delay(10);
      digitalWrite(8, LOW);

      Taster_1 = digitalRead(7); //refresh value of variable
    }
  }
}

Dieser nicht???:

const int Motor_1 = 10; //Motor
const int Motor_2 = 11;
const int Fern_3 = 4; //Fern Vor
const int Fern_1 = 5; //Fern Rück
const int FERNON = 13;
int Start = 12; // start Motor
void setup() {
  pinMode(10, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(4, INPUT);
  pinMode(5, INPUT);
  pinMode(12, OUTPUT);//Start
  pinMode(13, OUTPUT);
}

void loop()
{
  digitalWrite(Start, HIGH);

  digitalWrite(FERNON, HIGH);
  {
    int Taster = digitalRead(Fern_3);//Fern Vor
    while (Taster == 1)//while the button is pressed
    {
      digitalWrite(10, HIGH);
      digitalWrite(11, LOW);
      delay(100);
      digitalWrite(10, LOW);
      digitalWrite(11, LOW);

      Taster = digitalRead(Fern_3); //refresh value of variable
    }



    {
      int Taster_1 = digitalRead(Fern_1);//Fern vor
      while (Taster_1 == 1)//while the button is pressed
      {
        digitalWrite(11, HIGH);
        digitalWrite(10, LOW);
        delay(100);
        digitalWrite(11, LOW);
        digitalWrite(10, LOW);

        Taster_1 = digitalRead(Fern_1); //refresh value of variable
      }
    }
  }

}

Wo ist der Fehler?
Wieso fehlt bei mir das Zeichen Codeblock setzen??
