>The APPLICATION table is the a_entity keyed into RELATION. My test data had the application related to four applicants, person, business, person, person. It worked the first time with the person names showing, but no entry in the second slot for business. I looked in the business table and discovered that I had forgotten to enter a value. I did so. I tinkered around a bit with the grid, for no good reason, and when I ran it again it was broken! Now the first column is blank, although I still see the rest of the columns. Can anyone tell me what I might have done??

I do not think that you take safe way. You may do it differently, adding this line to grid.init event
This.ColEntity.Controlsource="''+Thisform.ShowEntity(RELATED.b_entity)"

'ShowEntity' is form custom method:
LPARAMETER lEntity
IF lEntity=.t.
Return Partner.Name
ELSE
Return Business.Name
ENDIF
