at the top of the sidebar are five icons, the right one is "Groups"
Click on that, then below those icons the heading changes to "groups"
Click on the icon to the lower right of that, and it brings up a window, "Named Groups."
Click the NEW button there and get the "Select People" window where you select those with the facts.
Click on "Mark group"
Click "Select people by data fields"
Burial -- exists -- is true
AND -- Grave Location -- exist -- is true
That will only get you those people who have both of those facts, whether they are filled in or not.
You have to fill in the column headings and the fields to show in the report.
THANK YOU this worked very well.
