Field Added in Relationship table - fetch Dropdown Labels instead of Values.

Hello, I have successfully created custom field in relationship table (e.g. country field in accounts_contacts table).

I got success in showing the country_c field in subpanel also. But I am facing a problem here.
In database, value is stored as ‘United_States_of_America’ because my countries are coming from dropdown field.
I want to show it as “United States of America” just like normal DetailView or Subpanel is showing.

I tried to $app_list_string[‘countries_dom’] anyhow with suitecrm custom subpanel vardefs, but got no success yet.

I achieved above functionality using this video tutorial - Custom field in relationship tablehttps://www.youtube.com/watch?v=rSkVKhuEPnE

Any help is appreciated. Thanks in advance.

I am using SuiteCRM.
Version 7.11.4
