Forum:Need some template help

I need some help with a template. I want a template that, if an info box is left blank, the box won't appear. I've seen it on other wikis, but I don't know how to do it. Here's the link to the template I need help with: http://greegee.wikia.com/wiki/Template%3AFakegee

 * This involves the use of parser functions, specifically the  function. I think that the Help:Parser functions page has an example of how to hide table rows for empty parameters.  The 888th Avatar   (talk)  01:29, April 16, 2010 (UTC)
 * I tried that, but all it did was get rid of the line when I clicked preview. Is it supposed to do that, or did I do something wrong? Bwog 13:46, April 18, 2010 (UTC)
