So with my code below im really stumped on whats happening. I've looking on the internet and looked at a bunch of code and it seems to be similar to mine but i have no clue why mine isnt working. when you click on the next(or any page) link it just displays an empty page. it might be a really simple solution or just a dumb mistake on my part on the code but i just cant figure out whats happening.
<?php
