I Am Confused And In Need Of Help, I Admit It...

Again there is something that does not work, but I cannot figure it out where I got it wrong.
Basically, my problem is this: i have a movie made of different scenes. In one of the scenes there is a menu with several buttons. The scene has code controlling the buttons like the following:

ActionScript Code:
this.activitymovie.activity.onPress=function(){    locat="activity.swf";    gotoAndStop('Naveng',1);}

In the scene that is called (Naveng) I have the following code:

ActionScript Code:
this.sections.load(locat);

which should be loading the relevant swf file in a loader (sections) on the stage. Unfortunately nothing loads. I tried tracing locat on Naveng, and the result returned is correct. Where is it that I am going wrong?
