next level

Hello Hive, this is StonemaulMidget, I am interested in experimenting with carrying heroes over to one chapter to the next. How do I proceed?

Can you guys help me see what I'm doing wrong? I'm basically trying to create a campaign, but the problem lies for me in trying to carry the hero from the first map to the next. I've loaded other people campaign to see how they do it, and I feel like I have done it correctly but I still can't...
