Thanks Joe, That was what I was kind of looking for. I am also thinking about the way I design application. I find that a lot of my app's are not very flexable. If someone wants to have a new field in a form or a new page added in between two existing pages. I find it causes me a lot of re-writing to make these simple changes. Does anyone have any tips that could help me design better code.
