Percentage preloader w/load bar frame 3 problems

I’ve been able to set up the preloader without any problem. However, in frame three I have the following code:

loadMovie("mymovie.swf",1);

It almost works. After the preloader is at 100%, it just stops. The external swf doesn’t load. I’ve tried putting play(); at the beginning of it but it didn’t help.

This is crucial since I need to be able to load external swfs via buttons once the first swf loads.
