A few imprecise points there. After clicking the question mark button you also need to click SHOW ME HOW, like when you activate the script. Also, it's the Generic script, not the Trivial script. The Trivial script changes game preferences before launching EB, while the Generic script runs a set of commands that you program in. By default it toggles perfect spy. I know, poor choice of names, and easy to be confused.
Other than that, follow Apgad's advice. Read up on the links he gave you.
