I've made this template Template:Scenario on the Empire Earth Wiki. It's the first time that I've made a template that's more than just an infobox and so far its been alright.

But I've been trying to figure out how to make it so if there is no input in the "Trivia" section then the Trivia header will not show, but so far have been unsuccessful. Could someone help me out here please? It's marked out by comments in the source edit mode.

Oh, and another thing. I keep trying to change the Template Type from Infobox to Unknown ('cause I really don't know how to classify it) but it keeps saying "Unfortunately we were not able to save this template type. Would you mind trying again?"
