Mouse over to play movie clip

Truly basic question I know but I can't seem to find an answer elsewhere and you don't even want to know how long I've spent on this. I'm trying to create a button that plays a movie clip and stops when it's moused over. I've attached a file (help.fla) that illustrates my problem. I'm working in CS4 Flash (not sure if that's the same as MX04? Didn't see it on the pull down list) Your help would be more than appreciated! Thanks so much.

You don't need to use gotoAndStop. Just stop(); will do. The following will stop the movieclip on rollover:

PHP Code:

---

blue_mc.buttonMode=true;
blue_mc.addEventListener(MouseEvent.ROLL_OVER, mcOver, false, 0, true);

function mcOver(e:MouseEvent):void {
    blue_mc.stop();
}

If you want it to stop and then start again the next time it is rolled over you need to test to see if the movie is playing or not using an if statement.

PHP Code:

---

var mcplaying:Boolean = true;
blue_mc.buttonMode=true;
blue_mc.addEventListener(MouseEvent.ROLL_OVER, mcOver, false, 0, true);

function mcOver(e:MouseEvent):void {
    if (mcplaying == true) {
        blue_mc.stop();
        mcplaying = false;
    } else { 
        blue_mc.play();
        mcplaying = true;
    }
}
