Transitions loading external files

1

I found the tutorial about how to do this and it works to a certain degree. i have the main choices which then lead to a submenu which is an external swf, then the buttons located in these submenus load other swf’s as content. for one section i want to experiment with transitions. i cant get the outro portion to work. the swf loads the way it supposed to but when i load the next swf the other one simply disappears. theres 2 empty movieclips in which the submenu’s and content that get load into … for the buttons its _root.whole.buttons and _root.whole.main for the content. is this why it is working any suggestions would be greatly appreciated thank you.
