Simple Form Dropdown Menu

Hi, I wonder whether someone could help me please. I'm trying to put together a dashboard which is set out as follows: - Timepicker - List of usernames which is filtered by the timepicker Then when the user selects the timepicker and the username I would like this to extract the relevant data in the dashboard panel. This is the 'simple XML' for this part of the dashboard:

Irrespective of what user I select in the drop down menu, the panel displays the results for all users. I've been through the various example online but I still can't get this to work. I just wondered whether someone may be able to look at this please and let me know where I've gone wrong. Many thanks and kind regards Chris
