Things to remember:
When using $_POST['submit'] to check if the file has been submitted, FFS make sure you name the submit form 'submit' in the input tag.

Also, $HTTP_POST_VARS apparently does not work with PHP5, nor does $HTTP_POST_FILES. The latter is $_FILES. The former..?

Wow. So I spend about 3 hours making a simple file upload script. Why 3 hours? A while was spent realizing that I'm working out of a book that uses old commands. That's frustrating. Then I realized I wasn't moving the uploaded file to my directory because of permission issues. I turned the permissions to read/write/execute for all users. That's probably not a good idea, right?

How would one fix this issue? PHP safe mode is already off, and I couldn't find the apache configuration file that would let me turn off safe mode for that site. I'm guessing it all came down to the fact that the directory was guarded.
