Can anyone help me understand how to use a Formula (Text) to get a value from the database. I'm doing a Customer search and am trying to group by Territory. When I use

{territory}

it gives the territory name, but I want the primary key of the territory. I've tried

{territory.id}

,

{territory.internalid}

,

{customer.sales_territory_id}

and more, but none of those work. Can anyone help me get the primary key of the territory in a search?
