UI Button Movement Problem

Basically what i'm trying to do is move every button down that is under the pressed button so that a panel under it would show up. However, the script I have does most of that but there's a problem. Whenever i press on one button and then press on another, the buttons under the last pressed button move to the wrong position. Does anyone have a fix for this? Here's the script:

 public GameObject[] buttons;
 public GameObject[] exp;
 public int nmbr;
 public int timespressd;

 public float move;     // Time taken to move
 bool pressed;
 public float step; /// speed of movement

 public void button ()
 {///check how many times buton was pressed
     
     if (move == 0) {
         timespressd++;
         pressed = true;
         move = 0.5f;
         nmbr = 0;
     }
 }

 public void button1 ()
 {
     if (move == 0) {
             timespressd++;
         pressed = true;
         move = 0.5f;
         nmbr = 1;
     }
 }

 public void button2 ()
 {
     if (move == 0) {
         timespressd++;
         pressed = true;
         nmbr = 2;
         move = 0.5f;
     }

 }

 public void button3 ()
 {
     if (move == 0) {
         timespressd++;
         pressed = true;
         move = 0.5f;
         nmbr = 3;
     }
 }

 public void button4 ()
 {
     if (move == 0) {
         timespressd++;
         pressed = true;
         move = 0.5f;
         nmbr = 4;
     }
 }

 public void button5 ()
 {
     if (move == 0) {
         timespressd++;
         pressed = true;
         move = 0.5f;
         nmbr = 5;
     }
 }

 public void button6 ()
 {
     if (move == 0) {
         timespressd++;
         pressed = true;
         move = 0.5f;
         nmbr = 6;
     }

 }

 public void button7 ()
 {
     if (move == 0) {
         timespressd++;
         pressed = true;
         move = 0.5f;
         nmbr = 7;
     }

 }



 void Update ()
 { 
     
     if (move <= 0) {
         pressed = false;
         move = 0;
     }
     if (move > 0) {
         move -= Time.deltaTime;
         if (timespressd % 2 == 1) {//////go up  ----    first time pressed
             exp [nmbr].SetActive (true);
             for (int x = nmbr; x < buttons.Length + 1; x++) {
                 buttons [x + 1].transform.Translate (Vector2.up * -step * Time.deltaTime * 2);
             }
         }
         if (timespressd % 2 == 0) {////////go down,even number
             exp [nmbr].SetActive (false);
             for (int x = nmbr; x < buttons.Length + 1; x++) {
                 buttons [x + 1].transform.Translate (Vector2.up * step * Time.deltaTime * 2);
             }

         }

             


     }
 }
