loadMovie - Changing .swfs

I have blank movie clip that loads a .swf when my site loads. When that .swf loads it plays a video. I simply use this script in the timeline in the actions layer:

target.loadMovie(“coachGameDay.swf”);

When this .swf is done playing the video, I want it to load another .swf, without having to use a button function.

Now I’ve simply moved the same script down the timeline several hundred frames, and changed the .swf in the script. It kinda works.

But depending on differences of connection speed, and browsers, it varies on when it hits that frame in the timeline.

Would someone be willing to point me in the right direction for a tutorial, or suggest how to write a script for this.

Thanks,
