Problem WITH BUTTON DETECTION

omg! I need help, so for the first bit of the code for my servo motors, I used a state change detection for a push button. Now I am trying to use a push button to move a stepper motor. I the state change detection is messing with that my stepper motor button. any thoughts on how to fix that.

/* PLATFORM - one click of the button goes to 0 degrees, the next
 click would make it go to 180 degrees and so on and so one 
   Stepper Motor- pendulum type code */
 
  #include <Wire.h>
  #include <VarSpeedServo.h> // custom speed library
  #include <Adafruit_MotorShield.h> // library for shield driver
  
  // Create the motor shield object with the default I2C address
Adafruit_MotorShield AFMS = Adafruit_MotorShield(); 
// Or, create it with a different I2C address (say for stacking)
// Adafruit_MotorShield AFMS = Adafruit_MotorShield(0x61); 

// Connect a stepper motor with 200 steps per revolution (1.8 degree)
// to motor port #2 

Adafruit_StepperMotor *myMotor = AFMS.getStepper(200, 2);

// SERVO MOTOR 

// this constant wont change:
const int servobutton = 2;
const int servopin1 = 9;
const int servopin2 = 10;
const int stepperbutton = 8; 

//declaring servo#1 as servo1 and servo #2 as servo2
VarSpeedServo servo1;
VarSpeedServo servo2;

// Variables can/will change:2
int buttonPushCounter = 0;
int lastButtonState = 0;
int stepperval;

void setup(){
  // initialize the button pin as a input:
  pinMode(servobutton, INPUT);
  pinMode(stepperbutton, INPUT);
  //initialize the servo motor to servopin 1 and 2
  servo1.attach(servopin1);
  servo2.attach(servopin2); 
  AFMS.begin();  // create with the default frequency 1.6KHz
  //AFMS.begin(1000);  // OR with a different frequency, say 1KHz
  myMotor->setSpeed(50);  // 10 rpm
  Serial.begin(9600);
}

void loop(){
  stepper();
   // FOR SERVO MOTORS
  //read the pushbutton input pin:
int sbutton = digitalRead(2);  
  //compare the state of button to its previous state
  if (sbutton != lastButtonState) {
  // if the state has changed, increment the counter
  if (sbutton == HIGH) {
    // if the current state is HIGH then the button went from off to on:
    buttonPushCounter++;
          Serial.println("on");
      Serial.print("number of button pushes: ");
      Serial.println(buttonPushCounter);
  } else {
    // if the current state is LOW then the button went from on to off:   
          Serial.println("off");
  }
    //delay to avoud bouncing
    delay(50);
  }
  // save the current state as the last state, for next tie through the loop
  lastButtonState = sbutton;
  //move after every 2 button click
  
  if (buttonPushCounter % 2 == 0) {
    //after the first button click, the servo motor will move to 180 degrees
    servo1.slowmove(180,10);
    servo2.slowmove(180,10);
  } else {
    //every secound click, the servo motor will move back to 0 degress
    servo1.slowmove(0, 10);
    servo2.slowmove(0, 10);
  }
}
void stepper() {
   stepperval == digitalRead(stepperbutton);
   if (stepperval == HIGH) {
  Serial.println("on");
  myMotor->step(100, FORWARD, SINGLE); 
  myMotor->step(100, BACKWARD, SINGLE); 
  delay(50);
   } else {
  Serial.println("off");
  delay(50);
 }
}

How ARE the switches wired? That is critically important.

What does the code ACTUALLY do? How does that differ from what you want? "I the state change detection is messing with that my stepper motor button" is completely useless information.
