The first thing you and your partner should do is download the starter file for this laboratory. Discuss it; in fact, go line-by-line, and figure out what the code does. Good pair programming practice, as you recall, requires a great deal of communication. If you're unclear on something, ask a colleague or myself.
You should, naturally, run it as well. First, switch DrScheme into the Module language, and then load and Run the source. The controller is the frame containing the slider, and the view is the color swatch. I have separated them into two separate frames so that you can easily see the distinction.
