hey everybody, i am new with max and i have a problem that i think is an easy one... i am working on a project that every sensor controls on a different movie- i have 2 sensor that when they both on they need to play third movie, but only when they both on. sensor a plays video a , sensor b plays video b ,and sensor b+a plays video c. how can i do that?

and with a different sensor in the room (sensor D) im looking for a way to switch between 2 movies with the same sensor- like when sensor D is off he plays movie1 and when he is on he plays movie2...how can i do that?

Im uploading my project i hope itll make things clearer...
