Hello David, Thanks very much for jogging my memory. I was not trying to do anything out of scope but just have re-usable functions that I can call in other controllers. I moved the getCart, and totals into the cart model and was able to greatly simplify my code. Everything is working like a champ.
Thanks for the help from everyone.
