Displaying Outlook Calendar Events: bubble Calendar Element

Hi all. This really has me stumped.

This is challenge 1.
From the Dropdown (upper left) users can view their Outlook Calendars by name. When an individual calendar is selected the RG is to display the corresponding calendar & events. I just can’t seem to make this work.

The Data source (Calendar A) always kicks back. I’m out of ideas.

Challenge 2. It deals with not being able to create an event that doesn’t come back with an UnableToDeserialize error. But, we can deal with that one later…
