Animation plays automatically

Hello everyone, I have a problem. When I press a button in the panel, I want the panel to slide away with the button and another panel to come.
But when I press the first button, the panel I want opens, while the other panel does not go. All the codes I wrote for the animation of the panel do not work.
I am trying to make an android application. I am associating the code with the menu. The code plays automatically when I press the play button. How do I prevent this? Can you check my code?
I have another question, how can I combine animations of different objects in one code. For example, I will press the button and the panel will move to the right with a small animation, and another panel will appear. This event needs to be specific for each button.

Thank you in advance for your help and advice.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class MainMenuGoes : MonoBehaviour
6. {
7.  
8.     // Animator component reference
9.     Animator MainView;
10.  
11.     // Use this for initialization
12.     void Start()
13.     {
14.         // Getting game objects animator component
15.         MainView = GetComponent<Animator>();
16.     }
17.  
18.     // Update is called once per frame
19.     void Update()
20.     {
21.         // getting a touch and its position from input
22.         if (Input.touchCount > 0)
23.         {
24.             Touch touch = Input.GetTouch(1);
25.             Vector3 touchPos = Camera.main.ScreenToWorldPoint(touch.position);
26.  
27.      
28.                     if (GetComponent<BoxCollider2D>() == Physics2D.OverlapPoint(touchPos))
29.                     {
30.                         MainView.SetTrigger("MainGoes");
31.                     }
32.          
33.         }
34.     }
35. }
