Yeah the GOAT change and the Carolina click have totally different methods. Palmer posted a tutorial for the Carolina click to show that it was a different method. He came to it independently, but also points out that he doubts he's the only one to have come up with the Carolina Click concept.
GOAT works totally differently, and by the problem you're having....it would indicate that you're not doing either correctly, lol.
They're both cool changes, but neither of them are worth buying a DVD for. There are plenty of other things you should be thinking about other than a colour change when buying a DVD.
