  Update the Select Statement:
  
  If you have modified the attributes in the decision table, update the Select statement to include the correct number of attributes.
  Ensure that the attribute names in the Select statement are spelled correctly and match those defined in the decision table.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, test the decision table to ensure that the error no longer occurs and that the logic behaves as expected.
