Arduino motor switching. NEED HELP!

I am trying to make upa code where I can control a small motor with chip that act as a mosfet that I got from ebay.

I got this code to control one int in one way with a pot.

const int transistorPin = 9;    // connected to the base of the transistor
 
 void setup() {
   // set  the transistor pin as output:
   pinMode(transistorPin, OUTPUT);
 }
 
 void loop() {
   // read the potentiometer:
   int sensorValue = analogRead(A0);
   // map the sensor value to a range from 0 - 255:
   int outputValue = map(sensorValue, 0, 1023, 0, 255);
   // use that to control the transistor:
   analogWrite(transistorPin, outputValue);
 }

That one work rather well, but when I tried to make the next one.

float pressLength_milliSeconds =0;

int optionOne_milliSeconds = 100;
int optionTwo_milliSeconds = 2000;  

int transistorPin0 = 9;    // connected to the base of the transistor
int transistorPin1 = 8;

int buttonPin = 2;
 
 void setup() {

  pinMode(buttonPin, INPUT_PULLUP);
  
   // set  the transistor pin as output:
   pinMode(transistorPin0, OUTPUT);
   pinMode(transistorPin1, OUTPUT);

   Serial.begin (9600);
   
 }
 
 void loop() {

  while (digitalRead(buttonPin) ==LOW){

     delay(100);
     pressLength_milliSeconds = pressLength_milliSeconds + 100;

     Serial.print("ms = ");
Serial.println(pressLength_milliSeconds);
}
  
  if (pressLength_milliSeconds >= optionTwo_milliSeconds){
   // read the potentiometer:
   int sensorValue = analogRead(A0);
   // map the sensor value to a range from 0 - 255:
   int outputValue = map(sensorValue, 0, 1023, 0, 255);
   // use that to control the transistor:
   analogWrite(transistorPin0, outputValue);
 }

 else if(pressLength_milliSeconds >= optionOne_milliSeconds){
  int sensorValue = analogRead(A0);
   // map the sensor value to a range from 0 - 255:
   int outputValue = map(sensorValue, 0, 1023, 0, 255);
   // use that to control the transistor:
   analogWrite(transistorPin1, outputValue);
 }

  pressLength_milliSeconds = 0;

 }

It compiles flawlessly, however it does nothing in action. Can some one point out what I did wrong and help me adjust the code. :o :confused:
