Disposition Clean Up - Need Count of total incidents

Content

I have a report that counts the total number if incidents by disposition. But it does not include the 0 value.

I have two columns:

Disposition                                   Incident count
incidents.disp_hierarchy               count(*)

Format for Incident count column selected, Display as 0 for null.

-----------------------

I then tried 

Dispostion                                   Incident count
dispositions.disp_hierarchy          count(incidents.disp_hierarchy )

But i still don't get incident count to display 0.
