Well, if nothing is happening you need to figure out where the execution line is stopping! Try putting a print string before any code in the event, another in between “Goal Vector SET” and “AI MoveTo”, and a third and fourth on “Default, Success” and “OnFail”.
Then go test it. If the first one doesn’t go off, it’s not a problem with this code, it’s a problem further upstream, if the second goes off but a third doesn’t, it’s the AIMoveTo, and if all of them go off we need to re-evaluate.
