But what you want aren't found counts, they are counts of how many records with a specific value in a specific field exist in your database.
There are a number of ways to do that and each method has trade offs such that the best choice depends on what you want to do with these counts.
Since you describe a Cartesian join relationship and only want to display these counts...
Define a "count of" summary field in listings that counts some field, such as the primary key, that is never empty.
Put three filtered one row portals on your dashboard layout. Put this summary field as the sole field inside the portal row of each.
Set up each filter expression to filter for a specific value in the status and representation fields.
Great answer. Thank you.
