How to unable player to click on GUI button

Hello Guys !

I cant solve problem with GUI and player movment.

When my character level up, i can click on button to increase damage or health. But, when i click on this button he moves to location behind button. How can i fix that ?

I make buttons by GUI.Button and use texture/Rect.

There is my mouse script :

     void Update()
     {
         cursorPosition();
         if (!attack && !die)
         {
             if (Input.GetMouseButton(0))
             {
                 FindPosition();
             }
             MoveToPosition();
         }
     } 
 
     void FindPosition()
     {
         RaycastHit hit;
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         if(Physics.Raycast(ray, out hit, 1000))
         {
             if (hit.collider.tag != "AllyMob" && hit.collider.tag != "Enemy") 
             {
                 position = new Vector3(hit.point.x, hit.point.y, hit.point.z);
             }
             }
 
     }
 
     public void cursorPosition()
     {
         RaycastHit hit;
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
 
         if (Physics.Raycast(ray, out hit, 1000))
         {
             mouseposition = hit.point;
         }
 
     }
 
     void MoveToPosition()
     {
         if (Vector3.Distance(transform.position, position) > 2.2)
         {
             Quaternion Rotation = Quaternion.LookRotation(position - transform.position);
 
             Rotation.x = 0f;
             Rotation.z = 0f;
 
             transform.rotation = Quaternion.Slerp(transform.rotation, Rotation, Time.deltaTime * 10);
             controller.SimpleMove(transform.forward * speed);
             GetComponent<Animation>().CrossFade(run.name);
         }
         else 
         {   
             GetComponent<Animation>().CrossFade(idle.name);
         }
     }
