Good Afternoon Andrew,
Find my approach as reference below and stored in attached workbook version 10.1
From your workbook.
I dropped the custom Longitude and Latitude under Measures.
Bring Longitude to the columns shelf
Bring Latitude to the Rows shelf
Drag AccountNumber to Detail on the Marks card.
All is explained here

Thanks Norbert for your help, really appreciate it!
I've republished the same viz Workbook: REI Tool and the display is cutting part of the dashboard off to the right. Is there something I can do to adjust the way it is displayed once published. In my desktop view, it appears OK and is not cut off.
