Compiles fine on my machine. Can you copy the error message(s) from the console and add them to your question?

What is the error?

You are calling Camera.main – so you need a main camera. You can do this by selecting the camera you want as your primary camera, and changing the tag to MainCamera.

–edit–
Alternatively if you are creating your camera object by script, you can set the tag using this prior to calling Camera.main:

[cameraVariable].tag = “MainCamera”;

The camera gameObject is called MainCamera, and it's tagged MainCamera. So I don't know what the problem is.

 –

not the gameObject, the Tag of the camera should be MainCamera. It's a built in tag.

 –

I said it's tagged MainCamera if that's what your trying to mean.

I just deleted the script and everything works just fine.

For everyone’s reference, I ran into this error after importing Playmaker into one of my old Unity projects. The problem in my case was that one of the Playmaker scripts (CutToCamera.cs) has an instance variable of type Camera, and I also had a custom script class also called Camera, which caused a naming conflict. I copied the code from my Camera script to a new script called GameCamera, deleted my old Camera script, and assigned the new GameCamera script to my camera GameObject which fixed the error.
