Thanks zork, I will do just that
The problem was that Update from the AddElement didn't seem to fire more than once, I just couldn't get it to keep updating so it just did the update once and that was it, so when I entered combat the bar didn't appear. I had to add an OnUpdate script to the "Update" function for the element to get it to work, not sure if this is the best way to do that. I've wrote in my todo list that I want to rewrite it again as I'm not happy with it, when I do that I'll use your rThreat for ideas.
