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
