help with coding for a stepper motor

Thanks for the advice,

i have attempted to tidy up the formatting and code.

Below is the latest version. When i powered it up and triggered the motion sensor the stepper moved cw once. But it did not move ccw afterwards (to essentially return to its starting position). And when i triggered the motion sensor again the stepper didnt move at all.

#include <AccelStepper.h>

AccelStepper stepper (1, 3, 2); // name of stepper motor (1 = driver, pin 3 = step, pin 2 = direction)
int pirPin = 4;

int calibrationTime = 30;
long unsigned int lowIn;
long unsigned int pause = 5000;
boolean lockLow = true;
boolean takeLowTime;
int PIRValue = 0;

void setup()
{

  stepper.setMaxSpeed(1000);
  stepper.setAcceleration(200);

  Serial.begin(9600);
  pinMode(pirPin, INPUT);
}


void loop()
{
  PIRSensor();
}

void PIRSensor()
{
  if (digitalRead(pirPin) == HIGH)
  {
    if (lockLow)
    {
      stepper.moveTo(100);
      stepper.moveTo(-100);

      PIRValue = 1;
      lockLow = false;
      Serial.println("Motion detected.");
      delay(50);
    }
    takeLowTime = true;
  }

  if (digitalRead(pirPin) == LOW)
  {

    if (takeLowTime) {
      lowIn = millis();
      takeLowTime = false;
    }
    if (!lockLow && millis() - lowIn > pause)
    {
      PIRValue = 0;
      lockLow = true;
      Serial.println("Motion ended.");
      delay(50);
    }

    stepper.run();
  }
}
