loadMovie not responding

im using this method http://www.kirupa.com/developer/mx2004/transitions.htm to load movies and create transitions between them for my site… I have read the technique thoroughly and im fairly sure the code and structure I have used is correct however the loadMovie function called from an embedded swf is not doing anything and I cant work out why…

on the main timeline there is a container movie that the swf files are loaded into, the intro sequence is loaded through an action on frame 1:

_root.currMovie = “introsection”;
container.loadMovie(_root.currMovie+".swf");

this works no worries… but when the container is targeted from inside the introsection.swf movie nothing happens, this is the code used:

_root.container.loadMovie(_root.currMovie+".swf")

I have tried variations with this and nothing works… the container movie has the correct instance name and the code works from the main timeline but not from within another swf…

any insights would be greatly appreciated…
