steppermotor only few steps

Hi thanks allready for all the tips and hints.

This is what I've got, but there is something wrong in the code because it won't work.

const int stepPin = 3; 
const int dirPin = 4; 
int relpin = 12;
const int stepsPerRevolution = 200;

boolean running = false;
 
void setup() {

  pinMode(stepPin,OUTPUT); 
  pinMode(dirPin,OUTPUT);
  pinMode(relpin, INPUT);
  digitalWrite (relpin, LOW);
  Serial.begin(9600);
}

void loop() 
{
  if (digitalRead(relpin)==HIGH)
  running = !running;
    if (running == !running)
    {
      digitalWrite(dirPin,HIGH); 
      for(int x = 0; x < 200; x++) 
            {
            digitalWrite(stepPin,HIGH); 
            delayMicroseconds(500); 
            digitalWrite(stepPin,LOW); 
            delayMicroseconds(500); 
            }
    }


  else
      digitalWrite(dirPin,LOW); 
      for(int x = 0; x < 200; x++) 
            {
            digitalWrite(stepPin,HIGH); 
            delayMicroseconds(500); 
            digitalWrite(stepPin,LOW); 
            delayMicroseconds(500); 
            }
}

Can someone give me another help?
