[Mediawiki-l] #if not working properly even with parserfunctions extension

[Azurite]

Hi all,
I've been trying to get the Infoboxes to work on my Wiki ever since I 
upgraded to 1.10. I've managed to get the majority of the templates in 
place and everything, and I do understand that
ParserFunctions is required; I have it and it seems to be working fine. 
But for some reason, the #if: call isn't working, and any HTML that 
follows after it is showing up as if it were normally rendered, like 
<table> and so on.
Here's an example page: 
http://www.seventh-star.net/wikific/index.php?title=Yu-Gi-Oh
Is there any way to fix this? I've already checked out the 
ParserFunctions and Infobox pages on Wikimedia, and the Discussion 
pages, but there doesn't seem to be a solution to #if: acting finicky.
Help!
