Flag Specific Trigger

[Entigren]

Hi, I've been helping a friend with a map for a couple of days now. We are trying to go about the flag security in a new and somewhat unique way. However I need certain outputs to take place on whether the flag is in its respawn position or not. So I was thinking making a trigger that is activated by the set team flag. I have messed with the lua a bit but dont have much knowledge on it. I got it to a point where the flag can trigger it however a player had to be present in the trigger also. I would like it to be able to trigger with just the flag in it. If anyone could help me figure this out I would appreciate it. Thanks.
