Movie clip button:Down state

Hello guys

I’ve got button made from movieclip

  1. I don’t get the MouseEvent.MOUSE_DOWN or CLICK?

2)If I click my button either


btn_BMC.addEventListener (MouseEvent.MOUSE_DOWN, buttonClick);
btn_BMC.addEventListener (MouseEvent.CLICK, buttonClick);

function buttonClick (evnt:MouseEvent):void {
    evnt.currentTarget.gotoAndStop ("click");
}

…one of them it is the same. The main concern I’ve got is the down state.
I’ve got on the timeline labels, the last one is “click” where I placed the movieclip where is 20 frame movieClip.

OK when I press the button it shows only first few frames of the movieclip.
Do you have any idea why and how can I solve this Please? You know when I click it shows that movieclip and then goes back to up state…
