I am having so many problems, I'm not sure where to begin.

I thought everything was fine and working properly. I posted a blog that simply said testing and everything worked fine. I finished making my domain and went to do my first post and so many things went wrong. The first "testing" post shows up, but not my second real post. And it also won't let me delete any entries. I'm not sure what pages the problem could be on. Here is my URL: HTTP://HOWBRUTAL.NET. Maybe you could take a look and see what I mean? I have the following pages in my build-a-blog:

index.php- which has the code to display my blog.
update.php
updateindex.php
submitform.php
editcomments.php
process.php
archives.php
blogcomments.php
category.php
categories.php

Just let me know what code you would like to see and I can post it. Thanks a lot!

I think you've got some things mixed up somewhere. I think you need to run through the tutorial series again, and check your code against the originals to see where you might have gone wrong.
