Flag groups ensure that only one flag range is triggered, when multiple flag ranges are configured. Only the closest flag range is triggered.
This task has multiple flag ranges configured. Each flag range for this task has been added to the Power group.
The user completing the operator round enters 12.
If the flag ranges weren't grouped, Flag1 and Flag2 would be triggered - 12 is smaller than 20 (Flag1 Min) and smaller than 15 (Flag2 Min), but not smaller than 10 (Flag3 Min).
However, because these flag ranges have been grouped, only Flag2 is triggered - only the closest flag range is triggered. The Flag2 range (15 - 65) appears below the task's input box. If the Flag2 range has a message configured, the message will appear next to its range.
