Hi Sam,
as I said before: you CANNOT change the BG color of a single element in an array!
What is this "Count" you try to color? There is no such control/indicator in your image…
You still don't attach your VI, but just an image of a part of the (messy) block diagram.
Attach a VI to get better help…
Best regards,
