Need help spotting error.

There was an error I found but even after fixing it I still get the same problem. Here's the whole function:

Code (csharp):

1. function CheckView()
2. {
3.     var hit : RaycastHit;
4.     if(Vector3.Distance(transform.position, HexinHex2.transform.position) > SpotDistance + 5)
5.     {
6.         ViewBlocked = true;
7.         CanSee = false;
8.         return;
9.     }
10.     if(Physics.Linecast(transform.position, HexinHex2.transform.position, hit))
11.     {
12.         if(hit.collider.gameObject.tag != "Hex")
13.         {
14.             ViewBlocked = true;
15.             if((hit.collider.gameObject.renderer.material.shader == Shader.Find("Transparent/Diffuse"))||
16.             (hit.collider.gameObject.renderer.material.shader == Shader.Find("Transparent/Bumped Specular")))
17.             {
18.                 CanSee = true;
19.             }
20.             if((hit.collider.gameObject.renderer.material.shader != Shader.Find("Transparent/Diffuse"))||
21.             (hit.collider.gameObject.renderer.material.shader != Shader.Find("Transparent/Bumped Specular")))
22.             {
23.                 CanSee = false;
24.             }
25.         }
26.         if(hit.collider.gameObject.tag == "Hex")
27.         ViewBlocked = false;
28.     }
29. }

 

Not sure if I'm referencing the shaders correctly or what...
