Card Filter Display Selections with Zero Results

[michaelhaga]

Community,

  I need some assistance with getting a Card to display correctly.  I entered the DAX you see below and I need the Card to show all of those results, even when they are not present in the source data.  

Specifically, I need to be able to filter the visual by Open or Closed within the past 30 days.  I currently don't have any of those issues; however, I still want it to return a 0.  

Please help!
