Ha thanks for your comments spuz. Not sure what happened on #2 that I ended up posting broken code. For number #3, I don't think recur will work without changing the algorithm a bit. There are 2 recursive calls depending on the conditional, and recur needs to be last for it to compile. Also in my defense it works on my machine ;)

So, yes its a learning process. I'm updating the post. Thanks again for your comments.
