Stop looping?

Hi! I am new to Flash and I am a bit overwhelmed. I have managed to create an nice little animation, but I don’t know how to stop it from looping! I went into the Properties box and set it to “Stop” but it still won’t work.

Can anyone help? I’m sure this is so simple and I will feel really stupid once I found out how, but I am so frustrated cuz I can’t find any tutorials that teach you how to “Stop” your animation. ha ha
