Question about controls! (New to VS 2008, Not new to coding)

Due to circumstances my coding environment must change to VS 2008. Now, I am usually accustomed to more linux friendly platforms, which VS is most certainly not. Since I'm simply trying to get a firm grasp of ASP 3.5, I've decided to try and build a few controls. So I what I did was created a simple webpage using the built in FileUpload control, a Button, and a Label. I'm not new to HTML either, so It was fairly painless to get that code to function, and I did confirm a file ended up on my server where I told it to go. So now I'm trying to dive into what ASP seems to be all about, modularizing via controls! So here's the deal, all my code compiles, displays correctly...etc....but when I click the button to upload, I get a "Page Cannot be Displayed" error, and the file does not upload! Any Ideas? I'm pasting the code here.

Edit: It's worth noting that I'm using IE 6.0, and am using the "View in Browser" feature to test this in VS 2008. Thanks!
