NullReferenceException for reasons I don't understand.

I don't know why, I'm tired and I'm about to rip my god damn head off. Just, just tell me why this is happening to me.

Here are the two codes where I get them.

In the first scripts, it occurs at line 112, where it says

    if (Input.GetButtonDown ("Fire1") && rayhit.transform.name == "Reflector") 
             {
                 selected = rayhit.transform.parent;
                 angle = selected.eulerAngles.y;
             }

The other one appears in the second script at line 83, where it says

 GUI.Label (new Rect (0, Screen.height - 20, 200, 40), "Position (2D): " + Controls.selected.transform.position.x + ", " + Controls.selected.transform.position.z);

I know, it's obvious what the issue is, fixing is and isn't my issue, for the first one just put

 if (rayhit.transform.name != null) 

Right, well that does not work, at all, it just results in even more exceptions, I don't understand, I keep trying anything, but simple referencing these variables in any way results in a null reference exception in certain situations, I've been trying and trying, researching and researching, just to find out how to solve this.

I just don't get why it wont work.

It's probably something really simple and I'll once again feel like an idiot.
