Load movie from library into container

I am trying to load a movie from the library into a container located in the main timeline. The button that loads this code is located inside a movie clip.

I used as a guide the following kirupa tutorials: http://www.kirupa.com/developer/mx2004/transitions.htm

The problem is that the clip I want to load is not external, it is in the library. Please help me. Here is the actions I have for the on release state:

on (release) {
if (_root.currMovie == undefined) {
_root.currMovie = “contact”;
_root.container.attachMovie(“contact”, “contact”, 0);
} else if (_root.currMovie != “contact”)
if (_root.container._currentframe >=
_root.container.midframe) {
_root.currMovie = “contact”;
