Changing variables of other scrips and objects

Hello I have got 2 different objects and scripts.

At my PortalDetection.js script, when the player enters to the red portal I need to change team variable in my character.js as red. I have got if statement but idk how to change a variable which is at other script.

PortalDetection.js script:

 #pragma strict
 var RedTeleport : Transform;
 function OnTriggerEnter (Trigger : Collider)
 {
     if (Trigger.gameObject.tag == "RedPortal")
     {
         this.transform.position = RedTeleport.position;
         Debug.Log("Spawning As RedTeam Soldier");
     }
 }

Character.js script:

 #pragma strict
 
 var pName : String = "Esporta";
 var pHealth : int = 100;
 var pMoney : int = 500;
 var pLevel : int = 1;
 var pTeam : String = "None";
 
 
 
 function Update ()
 {
     if (pHealth <= 0)
     {
     KillPlayer();
     }
 }
 
 
 
     function KillPlayer()
     {
     Destroy (gameObject);
     }
