Four thoughts came to mind: 1. index damage so the query or relation is failing 2. Could there be other relations that 4D could go through to get from Sample_Animal_Link to Animal? Maybe 4D picked another set of relations to follow to get from here to there. Result is wrong selection of records. 3. Are you running this code from a button or a menu item while a MODIFY SELECTION or DISPLAY SELECTION is running? Sometimes 4D will not do certain relational things because it can “break” the MODIFY SELECTION or DISPLAY SELECTION if any of the tables in question are involved. 4. If you do a QUERY or QUERY WITH ARRAY instead of a RELATE ONE SELECTION, do you get the expected selection of records? If so then see #2 or #3 above.
