Description inside FancyBox


I tried to use this tutorial for my fancybox. It’s work but I want to make the title inside the box. So, I add this
helpers : {
title : {
type : 'inside’
But, the title doesn’t work. I tried to refresh a few times but nothing changes. I’m using jQuery (1.4.2) and jQuery.Fancybox (1.3.4) in unbounce.

Can someone help me?
Thank’s in advance
