Hi!  
I’ve got a movie with a few buttons in it. When you click on one of the buttons an external swf opens. At the same time a large, quare, white movieclip opens at the back of the external swf (the white mc is in the main movie). Okay, so for so good.  
In the external swf there is a close button. When you click the button, the external swf goes to frame 14 to show a short closing animation. The last frame contains the following code:

TweenLite.to(\_level0.contentback\_mc,1,{\_alpha:0});  
this.unloadMovie();

The first line is to make shure the large white mc becomes transparent again. The second line is - ofcourse - to unload the external swf.

The problem is that the first line doens’t work.  
When I trace the first line from the main movie, the output contains '\_level0.contentback\_mc;

Oh, and the external swf is loaded in an actionscript generation container (contentback\_mc).

Any suggestions how to make this work?

Thanks in advance!
