Rob, please add this information to your original thread that you reference. I've locked this one because it is really just a duplicate (though simpler) post of your original one.
Not all questions can be answered so if it is important that you get an answer then please contact Tableau Support directly. The vast majority of help in these forums comes from Tableau end user volunteers -- it really is a community effort. There are only a few paid Tableau employees that are dedicated to the forums and they can't answer all posts or have the answer to everything.
