Ref dropdowns - Cant show descriptions in the list only see record ids

[Diego_Espinoza]

Hi all, 3 months ago I managed to resolve this but now I completely forgot.

How can I see descrptions in ref dropdown instead of Ids? I did it time ago like this

Even if descriptions are shown, IDs are store, which is fine. I want somehintg similar now but cant remember what I touched and cant find it in my app, now I see the Person ID but need to search using Name and store the ID.

FYI: The table is the same! Is a referral program I want to include, so in table Client, I have a new client that will tell who did the reference, meaning an existing client.
