On Trigger Enter, if GetKeyDown "E" add 1 to another script.

OnTriggerEnter is called only once. My Solution:

     var CiboUP_Text : Transform; //Transform
         
         var target : Transform; //Target Script
     
     function OnTriggerEnter (other:Collider)
     {
     if (other.gameObject.tag == "Player") {
             CiboUP_Text.active = true;
            }
     }
     
         function OnTriggerStay (other : Collider) {
 if (other.gameObject.tag == "Player") {
          if(Input.GetKeyDown(KeyCode.E))
             {
             target = GameObject.FindWithTag("Cibo").transform; //Find Target
             target.SendMessage("AddCibo", 1);
             CiboUP_Text.active = false;
             }
 }
             }
         
         function OnTriggerExit (other : Collider){
          CiboUP_Text.active = false;
         }
