OK. So here is the most crucial help I am able to provide at the moment: read every single line of this thread. Download the images from it and study them, preferebly print them out, laminate them and keep them nearby, make sure you understand everything in there. If you have any questions regarding the information there, please ask, I will help you with that. While I am making fun of you, I do mean it at the same time, so do not ignore this. It will most definitely help you.
