External Path linking?

Howdy
i’ve been doing the kirupa tutorial -
Transitions Between External SWFs.
I got everthing working fine but then had to do my buttons on an external SWF which loads on top of the main movie.
Now i cant get the buttons to load in the other extrenal SWFs
The tutorial says -

If your buttons are not located on the main timeline, you will have to change the path to the container movieclip.

i can’t figure how to do this.
of course i could just “loadmovie” but then i’d loose all the transitions.

The SWF with the buttons is called “buttons”
The main SWF i’ want to load clips into is called “main”
The SWF i want to load is called “services”

Below is the actionscript im using on the button.
How do i change the path to link to the container clip?
Can u guys help me?
Thanks in advance

on (release) {
if (_root.currMovie == undefined) {
_root.currMovie = “services”;
container.loadMovie(“services.swf”);
} else if (_root.currMovie != “services”) {
if (container._currentframe>=container.midframe) {
_root.currMovie = “services”;
container.play();
}
}
}
