As you might be able to tell, I started doing this but it's leading to too many other problems. I think I'll have to learn dual path's later as it's just going to end up being another level of learning on top of everything else I've taken on. I appreciate the help everyone gave me on dual path's and have kept your replies to work with at a later date.
