Rolling Average on non-summarized data

I appreciate your response.  This method returned exactly the same bad result.  For a given date, the rolling average is the same as the sum for that date.

I did discover when fooling around with it some more that If i simply change the date field in the visual to a Date instead of a Date Hierarchy, all the functions I've tried begin working.  There's something about using that Date Hierarchy which breaks all these rolling average measures... 

At this point I have the visual working, I just have no idea why that fixed the issue.

Thanks for the help though!
