Id showing instead of name

I have created a record and saved the record. I now want to use actions to reference a another object. I am using a collapsible wrapper action

The last part of your reference is MLS_Name_r.Id. I think you want MLS_Name_r.Name

I tried that and it does put the correct name in field but when I try to save it says

Ohhh… I see what you are doing now… try two actions in the action sequence. The first action updates MLS_Name_r.Id and the second action updates the same field to MLS_Name_r.Name. I think that will work based on a use case I had a long time ago so I may not be remembering it correctly.

Same results.

Here is what works  {{{$}}}

Leave off the Id and use __c instead of __r
