While in DDE, change your current table to "Honor Roll". In the search boxes, you'll need to narrow it down to get to the data you want to clear. Either date stored, store code or year ID will help drill down. You'll then search the records. Take a look at them in table view to be sure they are the ones you want. Go up to the search bar URL and replace dde with usm. Check the box to delete, confirm delete, then re-run your honor roll.
