Sliding menu not working when imported

I am using a sliding menu based on POM’s sliding menu

I have imported this into flash mx pro 2004 and all works beautifully until i call that swf into the main swf, in which the slide does not slide at all.

I am a bit stumped and appreciate any ideas.

I am calling the swf into an mc by using

on (release) {
loadMovie(“sliding.swf”, container);

thank u! :puzzled:
