Rendering camera but calling code does not set it up as current camera ERROR!

Can someone please help me. I have been racking over this error for ages now and I can't seem to work it out. I am trying to RenderToCubemap. I have a couple of cameras setup in my scene and I have this script attached to a third camera. It renders to cube map but always throws me this error.

I highly doubt I will get much response though which sucks. Unity's support has swayed quite a bit recently.

Anyways here is my code:
I would really appreciate it if someone could help. Thanks.

Code (CSharp):

1. public void CreateCubemap()
2.     {
3.         // create temporary camera for rendering
4.      //   yield return new WaitForEndOfFrame();
5.         cubemap = new Cubemap(1024, TextureFormat.RGBA32, false);
6.         //  GameObject go = new GameObject("CubemapCamera");
7.  
8.  
9.  
10.         //   go.GetComponent<Camera>().cullingMask &= ~(1 << LayerMask.NameToLayer("BakeLayer"));
11.  
12.         // place it on the object
13.         //  go.transform.position = renderFromPosition.position;
14.         //   go.transform.rotation = Quaternion.identity;
15.         // render into cubemap
16.         GetComponent<Camera>().RenderToCubemap(cubemap);
17.         positive_X = new Texture2D(1024, 1024);
18.         positive_X.SetPixels(cubemap.GetPixels(CubemapFace.PositiveX));
19.         positive_X.Apply();
20.  
21.         positive_Y = new Texture2D(1024, 1024);
22.         positive_Y.SetPixels(cubemap.GetPixels(CubemapFace.PositiveY));
23.         positive_Y.Apply();
24.  
25.         positive_Z = new Texture2D(1024, 1024);
26.         positive_Z.SetPixels(cubemap.GetPixels(CubemapFace.PositiveZ));
27.         positive_Z.Apply();
28.  
29.         negative_X = new Texture2D(1024, 1024);
30.         negative_X.SetPixels(cubemap.GetPixels(CubemapFace.NegativeX));
31.         negative_X.Apply();
32.  
33.         negative_Y = new Texture2D(1024, 1024);
34.         negative_Y.SetPixels(cubemap.GetPixels(CubemapFace.NegativeY));
35.         negative_Y.Apply();
36.  
37.         negative_Z = new Texture2D(1024, 1024);
38.         negative_Z.SetPixels(cubemap.GetPixels(CubemapFace.NegativeZ));
39.         negative_Z.Apply();

42.     }
