At least there is no annoying music to accompany this attempt to present a technical subject. If you continue to use this technique consider the "audience". You should at lease increase the font sizes and may be use some type of step-wise presentation. The scenario you presented would have been much more helpful in my particular instance, if I had to guess less about the purpose and what you were really doing. Basically, all you effort did was show me that it is "feasible" to do what I want to accomplish. Thanks for trying.
