If your six values will never change you could create a form with six labels to display your values and six check boxes to tick. If you want the records to display on this form add a subform which is looking at your table. Use the IIF statement to select your records ie
IIF([Forms]![YourFormName]![Check1]= -1,"Value1","") Or IIF([Forms]![YourFormName]![Check2]= -1,"Value2",""
Add 4 more Or IIF statements. Value1 and Value2 are to match your data.
Hope this gets you started.
