Fellow MVP Victoria Yudin, goes to great lengths to explain how to report on Extender data. Extender can be a valuable time saving customization tool, but data storage can be confusing even to the pros. Remember that Extender stores data in separate tables according to data types and the only way compile the data is by creating Extender Views.
Also don't miss out on her previous article about Extender and SmartList.
Victoria provides great detail on how to accomplish this with screenshots that will help you understand the process from beginning to end. More importantly, let her know what you think about her work by dropping her a comment.
