O.K. but where is the interrupt in your program? I've had PBP for 5 or 6 years now and there are somethings I just don't get and I guess never will, plus people are "tight" with their code, I guess they think you might make money off of it, heaven forbid. But with Flowcode 5 they give 50 free hours of online courses, they have a forum where you can chat with the actual designers of the software and there are numerous examples covering just about every subject in-depth.
