Don't be afraid to ask Chris (ccstone) questions. He's got an incredible knowledge of these kinds of things, and doesn't mind helping. He just needs to know specifically what you're trying to do. The fact that you're trying to learn is even better!
So his last reply said he needs a picture of the window before he can help. I'd take him up on that - post a picture!
@JMichaelTX Jim, you might want to split this to a new topic. It's been too long for me to remember how to do this.
