Currently in your cart it isn't making the call to compute the taxes, but it is making the call to commit the order. This is why you are getting the error message you are seeing.

It may be possible to get the two modules working together but it will take some coding changes. I can try to see if there is a simple fix for this. I will give it a try and let you know.
Thank you much
