Object moving problem

I am trying to move objects in array up or down for a certain amount of time when a button is pressed. This seems so simple however it does not work and I have tried many different ways to do it. Can anyone help? Here is the script:

public GameObject[] buttons; public Button[] panels; public GameObject[] exp; public int nmbr; public int timespressd; public float move; bool pressed; public Transform there; public Transform thereup; public float step;

     public void button ()
     { 
             timespressd ++;///check how many times button was pressed
             pressed = true;
             nmbr = 0;
             move = 0;
             
 
     }

     public void button1 ()
     {
             timespressd ++;
             pressed = true;
             nmbr = 1;
             move = 0;

     
     }

     public void button2 ()
     {
             timespressd ++;
             pressed = true;
             nmbr = 2;
             move = 0;

     }

     public void button3 ()
     {
             timespressd ++;
             pressed = true;
             nmbr = 3;
             move = 0;

     }


     void Update ()
     { 
             if (pressed == true) {
                     move += Time.deltaTime;
                     if(move > 0.3f){//when the objects should stop movng
                         pressed = false;
                     }
                     if (nmbr == 0 && timespressd % 2 == 0) {
                             buttons [1].transform.position = Vector3.MoveTowards (transform.position, there.position, step * Time.deltaTime);
                             buttons[2].transform.position = Vector3.MoveTowards(transform.position,there.position,step* Time.deltaTime);
                                 buttons[3].transform.position = Vector3.MoveTowards(transform.position,there.position,step* Time.deltaTime);
                     }
                     if (nmbr == 0 && timespressd % 2 == 1) {
                             buttons [1].transform.position = Vector3.Lerp (transform.position, thereup.position, step * Time.deltaTime);
                             buttons[2].transform.position = Vector3.MoveTowards(transform.position,thereup.position,step* Time.deltaTime);
                             buttons[3].transform.position = Vector3.MoveTowards(transform.position,thereup.position,step* Time.deltaTime);
                     }
             }
     }
