Create a new event, select "Choose a pre-defined event", then select "Player busts out on the bubble". That will create a new event with the Trigger and Conditions already setup. The Conditions will be:
rank = (inTheMoneyRank + 1)
This event will be triggered for every bust out, but will only get selected for the one bust out where the player busts out on the bubble. Therefore, after you create it, move the event up in the Events list (press the "Sort Events" button) above all of your other events that are triggered by a player busting out. That way another event which is triggered by a bust out won't get selected when the "on the bubble" player busts out.
