Jason, thanks for posting a sample workbook, but you'll need to post a packaged workbook (twbx), the one you posted doesn't have any data in it. Meantime do you have a Country field included in your data and did you put this on the level of detail shelf?
Thanks for the note on the workbook. I grabbed the wrong file. Please see the attached twbx.
Re data questions: I do have a country field in the extract, and I did try putting it in the "level of detail" shelf. Still no go...
Bingo... I didn't realize it only picked up the first 3 digits.
Glad it was a simple solution.
