can't get relationship data pulled into a view

can't get relationship data pulled into a view

I have a view in which I am trying to pull data from two tables. (My form already uses a lookout field to link the two by ID.)

When I build my view, I can see the column properties has a place to pull in data ("related fields") from the second table. But all of the related fields that I select come up blank. The field headers are there, but there is no data.

What am I doing wrong? Is there some special scripting that I have to add to pull in this data?
