BTW, I can't manage those records from the Layout View either since the record IDs are linked to another table.
And what is a "Database Management Screen"?
Is this a layout?
Can you change the view to table view so that you can see the records and use the modify button to select what fields are visible in the table view?
You can also create your own layout based on the same table.
If you enter find mode and put a lone = into the field, performing the find will find all records where that field is empty. Then you can use Delete Found Set from the Records menu to delete them.
