The images already have other keywords assigned to them. I see how this will work, but I would have needed to apply the individual values first. I removed keywords from a few test images and your method works better than what I was doing before. Looks like I will just remove the keywords and reapply them afterwards. Thanks!
FYI: I am cataloging racers in a running event where every participant was assigned a different race number. Adding the racers number as a keyword allows them to search an online gallery and find their images.
