Case, Catch and Try.. Together???

Question

I am still having some issues in creating my tool bar for the app. I have decided to use a case structure to determin which button the user has selected. In doing so, I ran in to a problem with some of the code for one of the buttons. There is a small section which utilizes the "try" and "catch" methods? >sorry< and when nesting this in one of my case steps, I receive an error.. Control cannot fall through from one case label ('case 0:') to another If I take out the try / catch sections of my code, the case functions, but my app will not, correctly anyway. How can I nest a section of code within a case step which contains 'try' and 'catch' Thanks, Bob
