Need help with recovering health

Ok here is the story. I started learning how to make rpgs yesterday and I was goofing off trying to make a trap that hurt him and a healing circle that would continuously heal him until he had full (100) health. I made a for loop where if _root.health wasn’t towards 100 yet then it would play the movieclip which is where the health adds up in. And when I get out of the circle it doesn’t stop. I don’t even know if my way is possible, or going to look good. If someone has an idea on how to do this any better or has a solution to my problem please post here.
