Can't get buttons to work right

1

Ok I have this layout I’m working on. Kinda like a tester. I have all the coding I need but I can’t get the transition buttons to work. When ever you click on them it just stays at the external movie that loads at the beginning. Can anyone look at my coding and tell me what I need to do to make my External Transition buttons to work properly. Or is the way I’m doing it not going to allow me?
