Not to discourage you, but I have given up on that jig. I bought one of the new type (Mine's a Katie Jig by Marc Sommerfeld), where you move the wood and jig, not the router. Much more intuitive. I'm sure there are some people here who can help you, and you might want to watch a number of YouTube videos on making dovetails on a PorterCable jig until you find one that you can follow. I had to make diagrams and label my jig because it's hard to remember the little tricks and details when you only use it occasionally.
The more I do, the less I accomplish.
