Mysidia Adoptables Support Forum

I am following PTGigi's exploring system tutorial, and I'm making a page that will be shown whenever the person is offline. It's basically a small "cutscene" kind of thing where after a couple of clicks, someone asks you if it's the first time you are there or if you have been there before (if you click first time, brings up registration box, if you click been there before, it bring up a login box)

How do I make the signup or login forms show up?

My code so far:
Code:
<?php

$num = secure($num);
