For all the budgets for "November Meeting", how many of them had exceeded the budget?
'November Meeting' is an event name; remaining < 0 means the cost had exceeded the budget
SELECT COUNT(T2.event_id) FROM budget AS T1 INNER JOIN event AS T2 ON T1.link_to_event = T2.event_id WHERE T2.event_name = 'November Meeting' AND T1.remaining < 0
