Dynamic event handlers help?

I’m making a piece of flash used for a website banner, previously i’ve had very little experience with action scipt as i’ve made various animations only having to use simple functions such as “stop()” and i’ve made a never ending scrolling menu also, but now i want to have an event that “onPress” a small animation is played where the mouse clicked the banner. What would be the appropriate script to link the .swf i make to the “onPress” command? or what is the right command in general assuming it is that command
