Selecting and deselecting not working

 void selection()
     {
         ray2 = Camera.main.ScreenPointToRay(Input.mousePosition);
         if(Input.GetButtonDown("Fire1"))
         {
             if(Physics.Raycast(ray2,out hit2,100))
             {
                 if(hit2.transform.tag == "Player")
                 {
                     selected = true;
                 } else{
                     selected = false;
                 }
             }
         }
     }

For some reason i can't get this code to work, anyone have any ideas what i did wrong. There is no errors, and i have declared all the variables correctly.
