focus of play(); when it is inside a function

[jblastos]

Have a small MC that is used several times (in main time line and in other MCs). I have a pause function inside the MC, that should pause its play for a few seconds, regardless of where it is placed. This is the pause I'm using:

var nInterval = setInterval(Pause, 3000);

function Pause() {
    clearInterval(nInterval);
    play(); 
}

Only problem is the play() starts not only the timeline in the MC, but also the master timeline.

As the play() is inside a function in the MC, I can't seem to address the MC's timeline with commands like "this.".

Any help? I"m sure it is something simple.
Thanks!
