There is probably an error in what was specified in your Go To Related Records script step. Please post exactly what you specified and include a screen shot of Manage | Database | relationships.
A bit of clarification on terminology to reduce the confusion: A table is what you create in Manage | Database |Tables. Table Occurrences are the boxe found in Manage | Database | Relationships. You have not duplicated a table, you have duplicated a table occurrence.
You nailed the problem. I had the wrong table specified in the Get Related Records.
thanks so much,
