Text Prefrab problem

So i have prefrab with text mesh and script that changes its text and a script that is spawning it,but it is changing prefrab instead, not the gameobject. How can i change gameobject?Thanks!

Text script:

 public class Text : MonoBehaviour {
     
     public float min;
     public float speed;
     TextMesh text;
     public string score;
     // Use this for initialization
     void Start () 
     {
         text = (TextMesh)gameObject.GetComponent(typeof(TextMesh));
         text.text = score;
     }
     
 }
 Spawning script:

 public class SimpleEnemy : MonoBehaviour {
     
     
     public Transform Text;
     public float scoreDeath;
     // Use this for initialization
     void Start () 
     {
         
          Text.GetComponent<Text>().score = scoreDeath.ToString();
          Instantiate(Text,transform.position,Quaternion.identity);    
     }
 }
