Cant acces function in other script

Hi i am trying to acces function in other script on other object but i am getting this error: Assets/selecting.js(12,32): BCE0019: 'ToggleSelection' is not a member of 'UnityEngine.Component'. When trying to call a function ToggleSelection. What am i doing wrong?

First script:

 #pragma strict
 
 var hitInfo : RaycastHit;
 
 function Update () 
 {
     if(Input.GetButtonDown("Fire1"))
     {
         if(Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), hitInfo, Mathf.Infinity) && hitInfo.transform.gameObject.tag == "Unit")
         {
             var script = hitInfo.transform.gameObject.GetComponent("ToggleSelected");
             script.ToggleSelection();
         }
     }
 }

Second script:

 #pragma strict
 
 public var selected : System.Boolean = false;
 
 public function ToggleSelection() 
 {
     if(selected == false)
     {
         selected=true;
     }
     else
     {
         selected=false;
     }
 }
