conditional formating

[hollarindy]

I need a little help to finish this database off i uploaded. If you click on the reports button then final selection you can see that I have duplicates highlighted. What I need to do is highlight those two entries on other forms. If you hit the back button it takes you to another form (20 Selected) you can see I also have duplicates highlighted here however 33K6-4-3176-1 is not highlighted because it does not appear twice on this form. 33K6-4-3176-1 does appear on the Over Draw report. The final selection is comprised of items selected from the 20 Random and the Over Draw. I have duplicates that appear on each individual form highlighted. I need to highlight entries like 33K6-4-3176-1 that appear on both forms but are not duplicates on either individually. Hopefully this makes more sense if you can see it in the database.
