Visual Basic programming problem

Hello all;

I've been coding a small program for visual basic (Yes it's not a great language but I figured I'd at least give it a try), and I've stumbled upon a small problem.

Code: http://pastebin.com/rqeKiE76

Now, the code works fine until section 6 where the outputs stop showing and the program closes itself. I'm sure I've missed something obvious and so I'm asking you, any help would be apprecaited.

I don't know how many of you have ever met Dijkstra, but you probably know that arrogance in computer science is measured in nano-Dijkstras.
