"file" input type not passing variable

file upload

[unipus]

I've got a form that includes a "file" input box. But what I've discovered is that this input is not passing ANY information at all when the form is submitted. I'm doing a print_r on the $_POST var and it's simply not there. What gives?

oh, and the form is

enctype="multipart/form-data"

[unipus]

nevermind... I was looking in $_POST when I needed to be looking in $_FILES.
