Thanks Mark, I'll take a look. I want to put the business rules in the 
model as well. In fact I want to put as much as I can in the model 
because one of the problems we have had over the years is having 
different programmers implementing almost the same business logic in 
different programs and the logic changes but not all the programs do... 
It would require a strange MVC setup to place that in the model.
