It depends on how you’ve setup your updates. If you followed the pattern above, just call Update HUD event every time you update your other variables (like Capture Status for example). So where you Call Update Capture Status, also put in Update HUD node.
If that sounds like too much work, you can setup a variable in the HUD and a direct bind. This works fine for most situations and will take care of HUD updates automatically. The only drawback of doing it this way is that it executes on every frame update, thereby potentially increasing your cost. It will work for your prototype but you’ll probably want to avoid that in the final product, hence I didn’t recommend that to begin with.
