how to stop the looping feature

[practice1111]

I have a one scene movie and I can't stop the looping.
I only want the effects to play once.
I unchecked the looping feature in the movie preview but that
doesn't stop the looping when the movie actually plays.
Please help if you can. Thanks so much. You can see the
movie at www.fcc.net/premier/swish/top5.html

Simple, Go to the very top of the timeline Right where Scene1 would be and go down the line and place a stop in the scene where you would like your movie to end.
