using macromdeia flash 8 to create a play animation button

ok i'm having trouble creating a simple button, that when pressed, plays the animation from another layer/ or same layer. Then once the animation stops it goes back to the first frame ( the frame where my button is, so the user can choose to press play again if they want to)
i've googled this, but it just seems that all the tutorials i've looked at didn't really tell me anything.
i've made my button like this: [Play] then once you click on it, it changes colour. The problem i'm having is that i dont reallly know how this action script works or if you suppose to add or change any of the default code that they give you.

Jam it back in, in the dark.

the actionscript for the first button is gotoAndPlay(); so would i have to put anything inside the () ...
heres a screenshot, i dunno if this will help

There's nowhere I can't reach.

THX~ it works...finally

This thing is sticky, and I don't like it. I don't appreciate it.
