Transitions between External SWF.s question

Hi there !

I have followed the tutorial on the transition between external swf. The problem i have is i cant get anything to load. I have buttons, and every button has an effect with actionscript in them, they are turned also into movieclips with instance names.

I put the container like in the tutorial, but when i try the movie it dosnt do anything.

could it be the actionscript the buttons have are messing the loading actionscript from the tutorial ?
