Toggle Visibilty on Text Issue

So I was trying to make it so that if you stand in a box collision for my “Goal” Object, that Text would appear around it. And after 3 seconds it would disappear until you entered again. For some reason It’s pretty buggy, it will sometimes show up but then not go away, sometimes the text doesn’t show at all, and sometimes the text flashes in and out rapidly. I’m not sure what I did wrong. Any help would be appreciated.
