GetComponent getting the whole Object instead of a script.

 var enemyUnit : GameObject;
 var enemyAIScript : EnemyAI;
 var enemyHuntScript : EnemyHunt;
 
 function Start(){
 
 enemyUnit = GameObject.FindGameObjectWithTag("Enemy");
 enemyAIScript = enemyUnit.GetComponent.<EnemyAI>();
 enemyHuntScript = enemyUnit.GetComponent.<EnemyHunt>();
 
 
 alert = false;
 caution = false;
 normal = true;
 }
 
 function Update(){
 
 if(alert == true && alertTimer >= 0){
         caution  = false;
         normal = false;
                 statusGUI.guiText.text = "ALERT : "+alertTimer;
         alertTimer -= Time.deltaTime;
         enemyAIScript.active = false;
         enemyHuntScript.active = true;
         
         
 }
 
 }

When I play in the editor, the line - enemyAIScript.active = false , disables the whole object ir's attached to rather than the script EnemyAI. Any ideas why ? Please help Thanks in advance Stealth
