C# Access to a variable by another script attached in a gameObject in the scene.

I want to access to a variable of the script "ExampleScript", which is put in a gameObject in the scene, called "player", and using it in the script "AccessVariabileScript".

This is the Player Script where there is the variable MyMoreSpeed:

 using UnityEngine;
 using System.Collections;
 
 public class ExampleScript : MonoBehaviour {
  
  //SpeedBall 
     public int myMoreSpeed = 0;
 
     void OnTriggerEnter(Collider other){
     if(other.gameObject.name == "MoreSpeed"){
  myMoreSpeed++;
  }
  
  }

Now, in another Script I want to access to the variable myMoreSpeed and, if this variable is >= 1 do somthing, in that case by touching the screen of an touchscreen and, if the myMoreSpeed is >= 1, the speed change.

I tried to do a c# code by myself. But it was useless.

This is the script:

 using UnityEngine;
 using System.Collections;
 
 public class AccessVariableScript : MonoBehaviour {
 
 public  float speed = 1; //<-- Normal speed
 public float speedUP = 2; //<-- If all the conditions are true, speed = speedUP
 public float speedA = 1;
 
 void Awake(){
  GameObject myPlayer = GameObject.Find("Player"); //<-- I tried to find the gameObject in the scene
  SpeedA = myPlayer.GetComponent<ExampleScript>().myMoreSpeed; //<--  ????
  
  }
 
 void Update () {
  //Simple movement 
  transform.Translate(0,-speed,0);
     //MoreSpeed. In this part of code I don't undertand why if I don't put "SpeedA >=1" works, but if I put it , doesn't work.
  if( SpeedA >= 1 /* I don't know if this is correct */ & Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began){
  speed = SpeedUP;
 }
 }

Unity3d doesn't report any error but the script doesn't work as I want.

Another question I want to ask you is how can I decrease The variable myMoreSpeed by 1 point, when the player touch the screen of an Touchscreen?

Thanks for the attention and if you found any typos I apologize, I'm Italian and I don't speak english very well.
