CUBE function/s to return Timeline selection

[mikeymay]

I have a Timeline that has a number of connections to Pivot Tables that are driving several charts.

I need to report on the dates selected via the time line but I am unable to get the CUBESET functions to work.

The Timeline is labelled as DateReceived where the shape can be named (same place as where you name a range)

Any help would be appreciated as I can't seem to get anything to work.
