OnGUI not working

I was going to make a GUI for my project today. So I made a JavaScript called testGui.js

This is my code:


function OnGUI()
{
    if (GUI.Button(new Rect(10,10, 100, 100), "Test")) {
        print("Test");
    }
}

`

But when I add it to the camera game object it I get an error:

MissingMethodException: Method not found: 'GUI.Button'.

`

Is your script called GUI? If it is it will hide the real functions…
