<div>Thank you so much for the quick reply! Guess I need to study the documentation more thoroughly.</div>
<div>When I say "explode", I mean I have to use many rules to represents 1 business rule expressed in human language. I believe the problem can be solved if the two questions in my last email are solved. Thanks again, Ingomar.<br>
